Why are you escalating to the extreme position of nukes? It's simple tit-for-tat aggression being called for, which you can argue isn't called for but it's not unreasonable. Nobody's called for nukes, just doing the same thing to China. You punch me I punch you. I don't murder your whole family.

There wouldn't even need to be a conflict at all. Just fly the balloons over their territory and see what they do. For all we know it could turn into a funny tradition where countries start ballooning one another. There are many outcomes where we can be remain friendly and on good terms without sitting down and taking the cuck position that anyone gets to violate our territory without response.
