Hamas and Hezbollah , ISIS were not attacked . Syria was attacked without a declaration of war, like pearl harbor or 911. Syria didn't threaten to attack Israel, they pose no real threat to Israel. A preemptive attack is only justified when there is an imminent threat of attack . We cant justify bombing Russia just because they have nukes and pose the threat to us. The Syrian airforce, or whats left of it . Doesn't pose any serious threat to Israel. Hell they didn't even retaliate!
Theres no justification for what Isreal did. They were trying to start a war . When the US said its pulling out ,Israel said no your not.
You don't know who was there, the fact that 4 Iranians were killed in this attack indicates this wasn't just an attack on Syrian Army. Hezbollah is fighting in Syria and is at war with Israel. If Russia is fighting terrorists in Syria, ALL terrorist groups should be included, not just those hostile to Assad. I know you want Israel to be wiped off the the map, but that's not Putin's position.
