How all-out war between Israel and its adversaries might play out

Matthew Savill, research director at RUSI, said Israel underestimated Hizbollah in 2006, in terms of both the movement's professionalism and its capabilities. "What they had in 2006 was decent tactics, knowing the territory and a lot of anti-tank weapons so they were able to surprise Israeli armour," Savill said. "It seems unlikely that the Israelis would be underprepared this time."
