The decision by the Trump administration to reduce US involvement with ROK counterparts in annual military exercises is best viewed in the context of recent high-level diplomatic statements issued by Washington. They reveal a great deal: President Trump has shown a lack of diplomatic expertise, exposing the White House to other considerations which include continual dysfunctional behaviour, questionable competence and also possible connivance in a sensitive and controversial area of recent ROK history.
The ROK is a key diplomatic ally of the US in northern Asia, strategically positioned for the defence of Japan doctrine. In fact, there remains little ambiguity in the US regional defence and security provision. Canberra has long acknowledged that 'since the Korean war, the US's key interest in Korea has been the strategic security of Japan'. (1) With the US-Japan alliance being upgraded to a global alliance, the strategic significance of the ROK remains extremely important, particularly in light of the close proximity of the northern DPRK and their alliances with Russia and China. (2)
The ROK also hosts nearly 30,000 US military personnel, many of whom remain long-stay residents and involved in sensitive military and security positions. Their tenure has enabled the US to gain involvement inside the ROK political system for generations; the contentious matter has resulted in a widespread political polarisation inside the country.
Cold War political tensions continue to run high on the Korean peninsula.
The ever-widening political cleavage in the ROK is based upon the fact and economic reality that closer trade relations with China has drawn the country closer to Beijing's sphere of influence. And, subsequently, closer to the northern DPRK.
Centre-left politics, which include the main trade union movement, favour moves away from the US toward a more independent foreign policy. The presidency of Lee Jae Myung in the Blue House in Seoul, for example, has become increasingly reluctant to be openly involved in US-led anti-China diplomacy; it is not in ROK sovereign interests. They tend to follow the line of continuing to be a US ally, while retaining a strategic co-operative partnership with Beijing, which is mutually beneficial. The centre-right, however, appear willing to accept any dictat from Washington and the Pentagon.
There is little common ground between the two competing sides, which continue to openly drift apart.
The position of the Trump administration would, therefore, appear quite clear. They are reluctant to be seen to openly support the present presidency of Lee Jae Myung and his ruling Democrat Party which was returned to office following an attempted parliamentary coup by previous president Yoon Suk Yeol in December, 2024. The Trump administration does not regard the presidential administration of Lee Jae Myung as being supportive of their Middle East foreign policy. (3) Or, at least, that was what was diplomatically stated by the White House. Questionable statements and policies are continually formulated in the White House, however, with the flourish of a pen; they change direction regularly like the wind.
In fact the exact position of the US toward the attempted parliamentary coup has never been accurately established; it would be almost inconceivable the White House and Pentagon did not know about the planning and implementation by Yoon Suk Yeol to seize power and unleash draconian measures to deal with the opposition. It was a classic Cold War drama, with alleged Fifth Columnists lurking in the shadows of the corridors of power in Seoul and other provincial centres. If the coup had proved successful it would have also served 'US interests', at basic face value. The fact that it failed has revealed a great deal about the changing balance of forces taking place across the ROK.
Much of the significance of the ROK for US foreign policy rests upon its annual Ulchi Freedom Shield joint military exercises, which involve massive mobilisations across South Korea, including civil defence. It is hugely symbolic. A decision by the Trump administration to 'substantially reduce joint military exercises with South Korea', can, therefore, be regarded as symptomatic of changing considerations. (4) Even an official statement issued by the ROK military noted the decision was considered 'unusual'. (5) The annual war games were cut at the final stages of preparation with only the first phase being used: the defence and security of the ROK against potential DPRK threats. (6) The second phase, running from 24-27 August, was postponed; it was focused upon a joint counter-offensive against the north. (7)
The moves, interestingly, have also been accompanied by a diplomatic statement that the US was planning to enhance 'fight tonight readiness, modernising the US-ROK alliance and shaping the security environment in North-east Asia'. (8) The diplomatically polite wording contained no details. It would, therefore, appear a convenient cover for something else.
That statement was also over-shadowed by an earlier diplomatic statement issued a few days beforehand which noted in a terse style that the US was 'seeking … to sustain a balance of power in the region … to secure their interests'. (9) It was accompanied with the matter-of-fact acknowledgement that the region 'is incredibly important, one of the most economic areas of the world. We need to take it seriously on its own terms'. (10)
The statement also included reference to the US not pursuing a foreign policy of fealty, but 'recalibrating … practical things: access, collaboration'. (11) But none would appear to be forthcoming. The US is experiencing difficulties accessing what it seeks0; it is not particularly difficult to assess the main factors of influence taking place.
A pressing issue confronting the US remains one of the unintended outcomes of their bombing of Iran earlier in the year. The Iranian response was to close the Straits of Hormuz, with far-reaching implications for Asia. Japan, for example, relies on the straits for an estimated 93 per cent of its oil imports, the ROK, relies on 90 per cent. (12) South-east Asia, centred on the highly diplomatically influential ASEAN trade bloc, has also been 'exposed to the current crisis … affecting … 60 per cent of regional oil imports'. (13)
The US turf war with China in the region has hit a major obstacle with its attempt to reassert traditional regional hegemonic positions. China became ASEAN's largest trading partner in 2009, and has continued to dislodge US interests since that time. (14) The fact that China also extends its influential trade links into Iran has only compounded the present problem.
The Trump administration appears, nevertheless, quite desperate to resolve the Iran issue; the Iranians, however, have more to gain from the US strategic blunder to attack their country. They are no strangers to diplomatic intrigue; the Strait will remain closed, indefinitely.
Well-placed diplomatic sources have revealed that 'the White House administration has pressed South Korea and other countries that depend on oil that transits the Straits of Hormuz for months to contribute to its efforts around the waterway'. (15) In fact, the US has diplomatically isolated itself over its foreign policy toward the Middle East; and failed.
Amid the diplomatic impasse well-placed sources in Washington have noted that there was a 'growing belief in Asia and Europe that the US is becoming an unreliable ally'. (16) It would appear based upon a wealth of reliable information and open-source intelligence data.
Moves in Canberra to continue to follow the traditional defence of Japan doctrine, for example, have already taken place with high-level meetings with Japan's defence minister, Shinjiro Koizumi. They seek to retain the status quo: a diplomatic statement noted concerns had been raised about the Trump administration and their recent involvement in the Korean peninsula. (17) An official diplomatic statement from Japan about the issue, moreover, noted, 'co-operation between … Japan … the US and South Korea was critical'. (18)
Meanwhile the Trump administration has continued to follow its Cold War foreign policy position toward the ROK with an official statement issued on their behalf by the influential think-tank the so-called US Studies Centre, that, 'the left in Korea … including some of the current administration in Seoul', remain critical of the US. (19) Even if the position was formulated with intelligence assessments, their relevance would appear questionable. It would appear more likely to cast further light upon possible US connivance and the attempted coup by Yoon Suk Yeol and its obsession with Fifth Columnists and the changing balance of forces away from traditional US hegemonic positions.
The so-called alliance Australia has with the US has become extremely and openly problematic, and also very dangerous: We need an independent foreign policy!
