I've always supported Israel unconditionally and cannot imagine a scenario where I wouldn't.
I have not supported Israel "always" unconditionally, I was especially concerned or even opposed to Israel´s policy around 2000-2003. But now, things have changed. It´s undeniable that Israel has been quite fair and moderate to its enemies (withdrawal from South Lebanon 2000 and from Gaza 2005), it has reached its hand for peace. But all it got in response was terror and violence.
Let the enemies of Israel reap what they sawed!
