Trump knows what he's doing, just ask Nettinyahoo. Trumps scheme is to utterly bamboozle the Iranians by changing the direction of the war every day. He's simply stopping at present because someone told him at the rate they were burning up armaments and military equipment, they'd have to stop fighting next week.
The 10 U.S. radar setups scattered around the U.S.-friendly Middle Eastern nations, destroyed by the Iranians in the last couple of weeks, have a total replacement value of nearly US$3B.
And those radars were crucial to determine the what and where of the incoming Iranian missiles, rockets and drones.
If you think it's been a costly couple of weeks for the Iranians, I can tell you it's been just as costly for the Americans. And those radar setups can't be replaced overnight - unlike Iranian Shahed drones.
Another massive equipment loss was the KC-135 tanker, about US$80M, plus about 120,000 litres of jet fuel. In addition, several other KC-135's have been damaged by shrapnel and drone attacks, taking more aerial refuelling ability out of the equation.
These U.S. losses are the reason the Yanks requested our Wedgetail AEW&C surveillance aircraft. Let's hope we don't lose it to some dumbf**k, trigger-happy Americans, or their Kuwaiti allies.
