The U.S. military is readying for possible conflict in the Pacific ahead of House Speaker Nancy Pelosi's possible trip to Taiwan in August, according to the Associated Press.

The Pentagon will escalate troop movements and security measures in the Pacific if Pelosi follows through with her planned Taiwan visit. China likely would not attack Pelosi's plane directly, officials familiar with the matter told the AP, but senior officials worry that her presence could inflame existing tensions between the U.S. and China over Taiwan.

"If there's a decision made that Speaker Pelosi or anyone else is going to travel and they asked for military support, we will do what is necessary to ensure a safe conduct of their visit," Chairman of the Joint Chiefs of Staff Gen. Mark Milley told the AP. "And I'll just leave it at that."

Officials declined to provide specifics but said measures could include fighter jets, ships and surveillance equipment to create redundant shields around Pelosi. China threatened to impose a no-fly zone over Taiwan if Pelosi visits and has dispatched warplanes into Taiwan's claimed air defense identification zone, CNN reported, as a possible countermeasure.
