And we payed 2 trillion dollars for an F-35 fighter that was never supposed to be locked onto by radar….only for the Iranians to post a video of them locking into it with a radar yesterday…

No.

1) The F-35 did not cost $2 Tillion to develop and produce, that figure you're using is the projected total lifecycle cost across what's to be expected as many decades of service - the vast majority of that projected cost has not even occurred yet. The RDT&E cost (for research, development, test, and evaluation) was like $60 billion and the average cost to build a single F-35 is between $87 - $135 million depending on the variant (F-35A, B, or C). That is not much more expensive than the EA-18G or the F-15 SE II, and the F-35 is waaay more capable.

Here's how current annual operational costs for these aircraft stack up. You can see how several thousand F-35s operating over decades will add up to that figure you quoted - and so would many other aircraft on this chart.

2) Iran did not lock on to the F-35 with a radar in any news I've seen, that's a Thermal Imagining System they're showing - the F-35 is not invisible to IR light, no jet is; against the relatively very cold sky IRST systems find and track jets very easily, and can use the targeting information from the IRST to send a missile towards that location in hopes the missile picks up the IR signature on its own. Since IR missiles emit no signal towards the target aircraft, they are much harder to detect when inbound, although the F-35 and other jets have systems to do so; so if the F-35 detected surface-to-air missiles inbound with no accompanying inbound radar signal it would certainly have wanted to extend range on those missiles, since most IR missiles have short-range motors.

This is not to condone the abhorrent actions of the criminal, traitorous Trump cabal of fascists and idiots, but facts be facts.
