Well ya know man, just like in real war, there were spies. I think it is important to remember that it's almost impossible to be strategic when you call out to to the ones who shouldn't be called for.. Even when you think you are talking to your own country. That being said, bomber missions, just like real war, should have escorts. If you are going to make it a "mission" you need to yell on country channel and get people interested. Even if there is a retaliation, your hoard should be too strong to stop it. Alt has a lot of power too, especially for bombers. The type of bombers you choose is also important for the type of dangers you may face..
don't let it bother you man, you just got spoofed,
