US President Donald Trump indicated that Washington is prepared for a prolonged military conflict, asserting that American munition stockpiles remain robust even as he claimed Iran’s naval and air capabilities have been largely destroyed.

In a post on Truth Social on Tuesday, Trump used the word “forever” while emphasizing US preparedness. “As was stated to me today, we have a virtually unlimited supply of these weapons,” he wrote, referring to medium and upper-medium grade munitions. He added that US stockpiles “have never been higher or better.”

The comments come a day after Trump said Operation Epic Fury was initially expected to last four to five weeks, though he made clear the United States was ready “to go far longer than that” if necessary.

Speaking alongside German Chancellor Friedrich Merz, Trump projected confidence about battlefield outcomes. “They have no navy, it’s been knocked out. They have no air force, it’s been knocked out. Just about everything’s been knocked out,” he said, describing the impact of ongoing US and Israeli strikes on Iranian military infrastructure.

However, senior defense officials offered a more cautious assessment. Under Secretary of War Elbridge Colby, testifying before the Senate Armed Services Committee, said the campaign remains in its early stages. “We are at the earliest stages of this campaign,” he noted, suggesting that a swift resolution may not be imminent.

Israeli Prime Minister Benjamin Netanyahu, by contrast, dismissed the prospect of an extended conflict. In an interview with Fox News, he said, “You’re not going to have an endless war,” arguing that Iran’s leadership is at its weakest point. He described the operation as intended to be “quick and decisive” and claimed it would create conditions for Iranians to establish a democratically elected government.

Meanwhile, financial markets reflected growing unease. Major US indexes, including the Dow Jones Industrial Average, fell about 1.3 percent after opening lower earlier in the day. Crude oil prices surged roughly 6.5 percent, heightening concerns over renewed inflationary pressures.

As military operations continue and diplomatic tensions intensify, uncertainty over the duration and consequences of the conflict remains high.
