The Department of Defense just disclosed that a US drone was fired upon over international waters last week (here). This is considered an act of war under international law. What happens next? Nothing? Tighter sanctions? War? Discuss.

International waters?
That is their side of story.
Iranians say other wise.
and I don't think anything will happen over this.
After all once washington downed their civilia\
plane too.

Iranians probably didn't like what the drone was doing... that's all I can think of at the moment.

As i said, Iran want to "show muscles", espeicely as USA is there target for blaming everything wrong with there country. So when they will pass the line there might be some tenssion, but i guese USA will leave it for now. It will be a stuiped move to attack now.

So, you think Iran is at fault here?

What I find to be of particular interest is 't that the drone was fired upon, but that after Iran suppossedly shot down a stealth Sentinel drone, two fighter jets can't bring this one down. So anycase Iran could make to shooting down the drone in the first place just took a cripling blow.

It was not shot downed, it was hack downed.

Except that the RQ-170 Sentinel doesn't use GPS as a guidance mechanism, instead using an inertial navigation mechanism.

Furthermore, if Iran has the capability to take down a stealth drone via hacking, why send two aircraft to down it as opposed to hacking it again?

Not all situations can use the same method. They likely didn't have enough time to intercept the transmission before the drone was gone, as opposed to a spying run where they literally have hours and hours.

This is a ploy by Iran to piss us off. They suck at killing Americans indirectly, so they want to provoke us into a war. That and it'll give them reason to attempt to bomb Israel.

Gotta kill our allies, too.

What makes you so sure?
and if it is so, it does not mean its unhackable.
Also had have it crashed on its own, it would have had been in a very bad shape.

Why the hell should I know?

1) The fact that the US Military, Fed, and independent groups have acknowledged the weakness of GPS systems, so much so that even civilian aircraft don't rely on GPS since stray beans can be picked up rather easily. So theres that, plus the fact that its military means there is a secondary system and may be even a third to make the drone resistant to hacking. But a Spoof attack is rather worthless because the GPS system isn't even the primary system. Your wiki article acknowledges this (source 17) and a quick perusal of sites using the search phrase "RQ-170 Iran spoof attack" confirms it.

2)   Of course. But Iran claiming they got in through a spoof attack when the GPS is t even the main system for guiding the drone is fishy at best.

3) the problem is that the only images Iran has released of the drone have been of a mockup that was showed to the state-run media. And the details of an RQ-170 are available on Wikipedia, so it wouldn't be hard to make a fake. And given the bat-wing design of the aircraft, an engine failure (it does, after all, have only one) would cause the aircraft to go into a lateral spin as it fell, dispersing energy and slowing down further from air resistance so that it could impact the ground and stay in relatively good shape.

To make a statement?

The only statement that Iran sent was that it can't intercept an aircraft worth squat. And if they can't do it in international airspace, it stands to reason they can't do it in their own airspace either.
