The program cost for the Grumman RQ-4 was just over 10 billion USD. A single unit cost 131 million USD.

I don't know where Gringo got that 200 billion figure from. I suspect he got it from from where he gets most claims he has made on this thread - his imagination.
As for Irans "measured and game changing" actions. All they achieved was blowing up Airlines Flight 752 killing 176 passengers and crew.
It is a minor quibble which demonstrates your lack of knowledge and understanding but the cost of the Reaper Drone shot down by the Iranians is given as $176b by Time Magazine, wikipedia(your favourite source) gives the cost as $222.7 made up of $131b unit cost and the rest R & D.
$200bn was reported at the time and the variance given makes that a reasonable average. Your doubting of it simultaneously demonstrates that
a) Your knowledge of Geopolitics amounts to a quick Google search and clicking on the wikipedia page.
b) You cannot even be arsed to read that properly.
Had you done so you would have saved yourself from looking so dumb now. Your figure that you "corrected" me with is from Wikipedia (the 131 billion figure). In your desperation to prove me wrong you forgot to read the full entry which gives £222 billion as the cost including R & D). So the one thing that you and Steve take issue with as inaccurate, as if to demonstrate the rest of the post is also wrong, is in fact accurate according to your own source which you couldn't even read properly.
I gave my figure from memory. I follow geopolitics keenly and can remember. I don't need to debate via Wikipedia entries wrongly quoted.
