The Israeli invasion of Southern Lebanon has already met strong resistance with eight Israeli soldiers killed as Hezbollah fighters used their network of tunnels and rocket launchers to fight back.
And while the war here intensifies the whole region is wondering how far Israel will go when it strikes back at Iran and possibly all its allies in Syria, Yemen and Iraq.
Almost a million people here have been ordered to leave their homes as Israeli air strikes continue to hunt Hezbollah leaders.
The skies are anything but calm: the entire region is bracing itself for yet more escalation.
