After 9/11, many Americans supported the invasion of Iraq and Afghanistan, and were making jokes about nuking them (a country that had nothing to do with the attack, by the way).
So were Americans fair targets?

Israelis are fed the with continuous far-right BS propaganda. I bet they believe Lebanese pray for their annihilation. This is yet another proof that controlling media work, and therefore democracies cannot function if media are not independent. No country, no people is safe for that.
