That was a direct response to your mention of property lines. International courts disagree with you and the constant public invasion and destruction of illegal Israeli settlements in both the West Bank and Gaza are pretty good evidence that you're wrong.
Correct, just as the us and others have backed Israel and provided support.
You're probably right, Israel certainly didn't care about them and Iran and the like are joining in because it benefits them any country would do and have done the same.
They don't care, the us will never back away from Israel. They see the bases there as integral to foreign defense. It's not particularly well known but the us operates a mountain top surveillance base in Israel which is a not unsubstantial part of why Iran is pissed.
