Ok, and why the hell they are bombing Beirut with such force now? 

Israel "democratic" title was given by the west and the terror they brought to their neighbors is sponsored by the west. 
Internationall comunity has been silence for decades about systematically stealing Palestinian land and That's just one of the reasons why hamas like cells exist. To resist the occupier. 

Isreal is systematically wiping out the country and it's people with our political leaders support. 

This conflict is neverending story and what Israel is doing right now is not a solution. It's a fertilizer for new terrorist groups. And we all know what terrorist groups are also good for? 

Excuse for mass control.
