The Pentagon is preparing to dramatically expand the American military presence in the Middle East as President Donald Trump weighs renewed attacks on Iran, with thousands of additional troops and a third aircraft carrier being readied for deployment, even as the conflict he has repeatedly declared “over” or “won” threatens to erupt into a new and potentially broader phase.

The Washington Post reported Thursday that the Pentagon is preparing options that could put as many as three US aircraft carriers and their accompanying warships in the Middle East.

According to The Associated Press, around 9,000 additional sailors and Marines are being dispatched aboard the USS Theodore Roosevelt carrier strike group and the USS Makin Island amphibious readiness group. The buildup could push the number of US personnel in the region above 20,000 by late October.

The Roosevelt is being sent to relieve the USS George Washington, while a third carrier, the USS George HW Bush, is also already in the region.

The new deployment plans come as diplomacy between Washington and Tehran remains stalled, and as Trump has repeatedly threatened to resume large-scale military action—including the total annihilation of the nation of over 90 million people—after the November midterm elections.

“Either they’ll do something very proper and smart, or they won’t be around very long,” Trump said of the Iranian government Thursday in Denton, Texas. “Frankly, I hate to see that, but they won’t be around very long.”

Iran, meanwhile, has reportedly begun preparing for a more expansive retaliation should the United States launch another major attack in the illegal US-Israeli war of choice against the Middle East nation.

Hamidreza Azizi, a senior Iran analyst at the International Crisis Group, told Reuters Thursday that the Iranian government seems “determined not to respond symbolically to a symbolic move and instead to escalate in the ⁠hope of reestablishing deterrence.”

Republican National Committee Co-Chair Lara Trump—the president’s daughter-in-law—warned during a Wednesday interview with British journalist Harry Cole that the increasingly protracted Iran War could not only tarnish Trump’s legacy, but could also cost Republicans next month’s midterm elections.

“Well, it’s possible,” Trump—who campaigned as the “peace president” on a promise of no new wars—said of the midterm risks Thursday on his way to Texas, before adding that “it should help because Iran will not have a nuclear weapon.”

The intelligence consensus of every US administration since former President George W. Bush—including during both of Trump’s terms—has been that Iran has not been trying to develop nuclear weapons.
