President Trump has one bright red line for Iran's nuclear program and some areas of flexibility as he weighs military strikes or a possible deal in the coming days.

The gambit was successful. At least twice, the president weighed ordering an attack on Iran, only to be dissuaded by aides from moving forward. But America now appears to be on the brink of war with Iran again. And this time, instead of acting as a deterrent, the Pentagon’s war plans are being used to draw up options for the president to consider.

U.S. military buildup in Persian Gulf intensifies as Trump deploys naval force near Iran. Aircraft carriers and destroyers position for potential strikes.

President Trump is pressuring Iran to either curtail its nuclear program or face military strikes, after Iran amassed a large stockpile of highly enriched uranium. Here's what to know.

Tensions between the United States and Iran have caused an increase in oil prices across the country and here in New Jersey, according to experts.

These are the first rallies on this scale since January's deadly crackdown on demonstrations by the authorities.

If talks fail, defence analyst David Des Roches said, U.S. activity in the Gulf already signals how any strike would begin: blind Iran’s air defence and then hit the Revolutionary Guards Navy, the force behind years of tanker attacks and threats to close the Strait of Hormuz, the route for a fifth of global oil.

A report said potential American military strikes on Iran could target individuals or pursue regime change, as the U.S. wants to reach a deal with Iran.
