One can tell many things. But in europe, there is not a big problem with gun violence. There still is, and it is great to find ways to counter them.
But no comparison to America.
I just assumed you are american, when you talk about Europe like this. It seems to me you do not know much how save it is here.
And it is quiet obvious you misunderstand something. There is no agressive action from NATO. NATO is a defensive allience. So NATO helps Ukraine to defend their teritory.
