Iranian intelligence has for three decades been slowly taking over Lebanon by means of agent recruitment to the degree that Hezbollah is not that far away from officially declaring Lebanon an Islamist state as modeled on Iran. Iran controls nearly all dimensions of the Lebanese state including the military, the government, the seaports, the airports and the judiciary. While still a secularist country, Lebanon is on the verge of becoming the Islamic Republic of Hezbollahstan or even becoming officially annexed by Iran.
The international community must internalize that the only way to prevent this from materializing is for Israel to militarily liberate Lebanon. Civil war in Lebanon is not an attractive prospect and the remnants of former militias which still hold some weapons would be easily defeated by the well-trained Hezbollah.
Only Israeli military liberation of the country will prevent a complete Iranian takeover of what used to be Lebanon.
