This is where you're lack of knowledge of the situation is shown.
Israel have attcked Lebanese army barracks. Thats a fact
The Lebanese army lack the capacity to resist the attacks by the Israeli Air Force, which is one of the most advanced in the world. Thats a fact.
Resistance on the ground is different. The Lebanese president and the Lebanese defence minister have said that if Israel try to invade then the army will protect Lebanon.
and finally, Israel have they're only targeting Hezbollah but they're hitting the whole nation. Lebanese infrastructure, airports, civilians, communication towers, factories are all being targeted. Im not making this up:
BEIRUT, July 23 (Reuters) - Israeli bombing of a crowded Beirut neighbourhood where Hizbollah had its headquarters has breached humanitarian law, a senior United Nations official said on Sunday.
"It is horrific. I did not know it was block after block of houses," Jan Egeland, the U.N. emergency relief coordinator, told reporters as he toured the shattered Haret Hreik district. "It makes it a violation of humanitarian law."
The British foreign minister has even stated that Israel is hitting the whole nation.
To put it simply, Israel are commiting war crimes as outlined by the Geneva Convention.
