What does Trump know about the shootdown of the US Apache helicopter?

Shooting down an Apache attack helicopter is a serious business. It's not like hitting a drone. So did Iran's Islamic Revolutionary Guard Corps target the helicopter with a crew of two on board? If the helicopter was hit by a missile, the chances are the two crew members would not have survived. But they were picked up safely. So, did the Apache collide with an Iranian drone? That also seems unlikely. The crew would be super-experienced and could evade a drone. Nevertheless, Donald Trump instantly blamed the Iranians and ordered Central Command to retaliate. Iranian air defence systems and communications sites were bombed. The rescued crew will presumably be able to give a better picture of exactly what happened. If it was an Iranian missile, then Iran got what it deserved. But if it turns out, it was a helicopter malfunction, then Iran is going to be very aggrieved. My feeling is that Trump, as commander-in-chief, must have been told something which convinced him it was the IRGC which brought the Apache down. In other words, the fantastic array of US surveillance aircraft around in the Gulf at the moment must have images of a missile or whatever heading for the Apache. If that's the case, then Trump's decision to retaliate was the right one. Central Command said the response was proportionate. Centcom is investigating. Meanwhile the ceasefire between Iran and the US has already been breached so many times that it puts in danger the "oeace" negotiations which, amazingly, are still going on to end the war and reach a settlement.
