Former House Speaker Newt Gingrich, a staunch supporter of President Donald Trump, has warned the president that Americans will not back his war against Iran "forever." Gingrich identified "three huge challenges" facing the administration, including keeping the Strait of Hormuz open, stabilizing the global economy, and dismantling the Islamic Revolutionary Guard Corps. He cautioned that if Trump fails in these areas, it will be "a step into quicksand."

Why it matters

Gingrich's warning highlights growing concerns among Trump's allies about the political sustainability of an extended conflict with Iran. As a longtime supporter, Gingrich's comments suggest Trump may be at risk of losing the backing of his base if he is unable to achieve clear victories in the confrontation.

The details

In an interview on Fox Business, Gingrich said he believes the public will support Trump "for a little while" in the conflict with Iran, but warned that support will not last "forever." He argued that if Trump succeeds in addressing the three key challenges, he will be seen as a "genius," but if he fails, it will be "a step into quicksand." Gingrich has occasionally parted ways with Trump in the past, including criticizing the president's immigration policies as being too brutal.
