The US is almost certainly playing a major supporting role.

That might be true, but look at how hyped Israel's Iron Dome has been as being so "amazing." And yet Yemen continues to make it through time and time again. Not to mention Hezbollah's many successful incursions with their recon drones and missiles hitting many of their targets. Hell, even the USA took some bad hits when dealing with resistance fighters in Afghanistan and Iraq. All the expensive tech is so focused on dealing with opponents that are also using it. Or at least pitched as important because of "the future of war that will be fought" and just seems to make mad profits for private corps and capitalists.

Are the systems impressive in fucked up scary ways? Yes, but it gives false senses of "safety" and allows for underestimating nations and fighters that are seen as "backwards" from a tech standpoint. That underestimating and hubris has caused many nations throughout history to lose. Of course it doesn't negate that it is kind of shocking that Iran hasn't found creative ways to better deal with these attacks. Though it does give them every green light to hit back as hard as they want/can.

Are you asking wether you heard an explosion from Tehran, all the way in western Germany?

'cause if so, no. You wouldn' t hear a nuke that far away
