In the third week of the joint US-Israeli war against Iran, Donald Trump faces decisions that could define the rest of his presidency.

But if the American commander-in-chief is grappling with a war of choice that seems in danger of spiraling in ways he can't control, those concerns are not playing out in public.

In more than an hour of public remarks at the White House on Monday, he discussed his thinking on the state of the war effort - and also on Kennedy Center renovations, White House ballroom construction plans, the World Cup, and other unrelated topics.

It was classic Trump, unscripted and wide-ranging. Over the weekend, he played golf at his Florida resort. On his Truth Social website, he devoted nearly as much time to railing about the Supreme Court as he did to discussing the Iran War.

While Trump may be interested in other topics, he is facing a familiar challenge to US presidents: war can consume a presidency whether they want it to or not.

Evidence suggests that a conflict Trump previously deemed already won might extend for weeks or longer. On Monday afternoon, he announced a delay to a planned presidential trip to China in response to the war.

White House Press Secretary Karoline Leavitt confirmed that the president’s primary responsibility as commander in chief is ensuring the success of Operation Epic Fury, the military operation against Iran.

The president recently revealed he was forming a coalition of international forces to secure navigation through the Strait of Hormuz, vital for global oil shipping, although many allies expressed disinterest in joining the effort.

Trump's current strategy includes a possible increase of US naval presence in the region, raising concerns about escalating military commitments. However, he has acknowledged the dangers associated with deploying ground forces in Iran, as public sentiment generally favors avoiding extended military engagements.

The situation highlights the complexities and risks facing Trump. While maintaining a confident public front, the potential political ramifications are significant, especially with rising energy prices affecting American consumers.

With midterm elections on the horizon, Trump must navigate these challenges carefully to sustain his political support, as the cost of living remains a pivotal issue for American voters.
