WASHINGTON, 21 May 2026 – The United States’ diplomatic machinery is facing growing strain as foreign policy decision-making becomes increasingly centralised around President Donald Trump and a small circle of advisers, raising concerns among allies over predictability, institutional continuity and America’s role in managing global crises.
The shift has become more visible during recent tensions involving Iran, Ukraine and Gaza, where foreign governments and U.S. diplomats have reportedly struggled to interpret Washington’s position after sudden public statements and policy signals from the White House. Traditional diplomatic channels, including embassies, the State Department and the National Security Council, appear to have been weakened or bypassed in several cases.
Nearly half of U.S. ambassadorial posts remain vacant, while more than 3,000 State Department staff have reportedly left amid restructuring, reduced institutional influence and the rise of politically aligned appointments. The result is a foreign policy system that allies increasingly view as unpredictable and more dependent on personal access than formal diplomatic process.
For foreign governments, this has changed how diplomacy with Washington is conducted. Instead of relying only on ambassadors, official policy desks or established intergovernmental channels, some allies and partners are turning to informal networks, business figures and individuals close to Trump to better understand U.S. intentions. This reflects a broader recalibration by governments seeking clarity in an environment where public rhetoric, private channels and official policy do not always appear aligned.
The impact is especially significant because the world is already facing multiple flashpoints. Tensions involving Iran have kept energy markets on edge, the war in Ukraine continues to test Western unity, and conflict-related instability in the Middle East has complicated relations between Washington and several allies. In this environment, uncertainty over U.S. policy can amplify market volatility, weaken diplomatic coordination and create room for rival powers to project stability.
China and Russia have already sought to use this moment to strengthen their own strategic messaging. During recent talks in Beijing, Chinese President Xi Jinping and Russian President Vladimir Putin criticised U.S. foreign policy and presented their partnership as a stabilising force in a fragmented global order. Their meeting underlined how perceptions of U.S. unpredictability can become a geopolitical advantage for rival powers seeking to reshape global influence.
The deterioration in global perceptions of the United States is also being reflected in public opinion data. A recent international democracy survey found that views of the U.S. had weakened for a second consecutive year and had fallen below perceptions of Russia, highlighting the reputational cost of strained alliances and unpredictable policymaking.
For allies, the challenge is how to maintain practical cooperation with Washington while preparing for sudden shifts in tone or policy direction. This is particularly important for NATO partners, Asian allies and Middle Eastern governments that depend on U.S. security commitments, trade relationships and diplomatic backing.
The hollowing out of diplomatic capacity also carries longer-term risks. Career diplomats provide institutional memory, technical expertise and crisis-management experience. When their influence declines, policy becomes more dependent on political loyalty, personal networks and rapid executive decision-making. That may allow faster action in some cases, but it can also increase the risk of miscommunication, policy inconsistency and diplomatic error.

The weakening of traditional U.S. diplomacy matters for Asia because American policy remains a key variable in regional security, trade, technology and capital markets.
For Asian investors, the concern is not only political drama in Washington. It is the market impact of uncertainty. When U.S. policy becomes harder to predict, investors may demand higher risk premiums across currencies, bonds, equities and commodities. This can affect everything from oil prices and defence spending to supply-chain decisions and foreign capital flows.
ASEAN governments, including Malaysia, must also navigate a more complex environment. The U.S. remains an important trade and investment partner, but China is deeply embedded in regional supply chains and infrastructure. If U.S. diplomacy becomes more personalised and less institutional, Asian countries may need to rely more heavily on diversified partnerships, regional platforms and pragmatic economic diplomacy.
The broader message is clear: diplomacy is infrastructure. Just like ports, power grids or data centres, it supports global stability. When that infrastructure weakens, the cost is not always immediate, but it can appear quickly during crises.
For businesses and investors, the priority is to watch policy signals carefully, avoid overreliance on any single geopolitical assumption and assess how diplomatic uncertainty may affect energy, technology, defence, trade and emerging-market risk.
