It is a great day for Israel!
I think it's more complicated than that. I agree, the land belongs to Israel and why does the world feel entitled to opinions about what Israel does on its own property? The Israeli-Palestinian conflict is a lightning rod, used by other countries (the west, Arab nations etc) as a distraction for their own misdeeds.
My problem with the embassy move is the way this was rolled out. The speeches made were not forwarding-thinking. They were singular and represented extremists and that's what Netanyahu is and represents: a narrow path forward for Israel.
Likewise the Palestinians align themselves with extremists who use them as pawns. The Palestinian civilians shot and killed today were setup by their own people. The Palestinians Authority called for a massive protest of unarmed civilians and encouraged them to rush the border. It's another PR stunt for the Palestinians to get world sympathy.
