Why does Israel get to keep its nuclear weapons?

[rajpoot]

Doctrines ain't worth the paper they are written on in such uncivilized states.

Umm...Doctrines aren't written on paper. Unlike treaties. To put it simply, they are more like a plan. Or something the plan is based on.
So unless you're basically saying that the uncivilized states don't intend to follow their own plans, your statement makes no sense.

Also I'd rather not get into debating who's civilized or what civilization means because that's moot, and usually ends with arguments which are little more than 'mine is bigger than yours'.
