**Trump's Return Sparks Global Tensions and Uncertainties**

Donald Trump’s re-election has reshaped the global political landscape, stirring anxiety not just among America's coastal elite but also across Europe, Iran, and potentially China. Voter dissatisfaction with high gas and housing prices, exacerbated by the Biden-Harris administration's last-minute immigration policy response, contributed to this seismic shift. Vice President Kamala Harris’s strong focus on issues like abortion, while largely ignoring controversies surrounding transgender athletes and diversity programs, may have further isolated voters.

Overseas, Trump's promise to mediate a settlement in the Ukraine conflict has raised alarms. With Trump's evident admiration for Vladimir Putin, Ukraine and its Eastern European allies are particularly nervous. There’s concern that Trump could pressure Ukrainian President Volodymyr Zelensky into conceding critical territories like Crimea and the eastern oblasts to Russia. In anticipation, the Biden administration is urged to expedite military support for Ukraine to bolster its negotiating position.

The potential implications for NATO are equally concerning. Trump has criticized NATO members for not meeting defense spending targets and has hinted at demanding even higher contributions. Although Congress has made it difficult for any president to withdraw the U.S. from NATO without substantial Senate approval, Trump could still disrupt the alliance by pulling the U.S. from NATO’s integrated military command.

In the Middle East, Trump's victory has been welcomed by Israel. The Israeli government expects more freedom in dealing with conflicts involving Hamas and Hezbollah. Trump’s previous "maximum pressure" sanctions on Iran are likely to be reinstated, anticipating a tougher stance against any attacks on Israel. This could lead to increased American military support for Israeli retaliatory measures.

Trump's affinity for leaders like Hungary’s Viktor Orbán and Turkey’s Recep Tayyib Erdogan signals a potential shift in America's diplomatic approach. Orbán may feel emboldened to challenge NATO and the EU further, particularly regarding Hungary's stance towards Moscow. On trade, Trump's campaign promises to increase tariffs to protect American industries will likely affect not just China, but also European and other Asian economies, causing particular concern in Vietnam.

While Trump's campaign proposals remain speculative, his transactional nature suggests flexible implementation. Nonetheless, America's allies and adversaries must tread carefully, as any missteps could provoke a decisive response from the Trump administration.
