"The latest developments, in which a diplomatic solution is emerging for Syria to be disarmed of chemical weapons, demand determined action and will be judged over time according to results," a statement from his office quoted Ya'alon as saying in an address to Defense Ministry staff.

"But it is proof to the countries of the free world that a significant and credible military threat, as applied at the beginning of the crisis, deters dangerous rogue regimes and is able to advance a diplomatic solution to disarming countries of weapons of mass destruction."
"In other words, he who seeks peace must prepare for war," the minister noted.
Under terms of the breakthrough deal struck in Geneva on Saturday between US Secretary of State John Kerry and his Russian counterpart Sergey Lavrov, the regime of President Bashar Assad has a week to hand over details of the quantity and location of all the chemical agents in its possession
Kerry paid a whirlwind visit to Jerusalem on Sunday for talks with Israeli Prime Minister Benjamin Netanyahu, and warned Syria that it was not off the hook yet.
"The threat of force remains, the threat is real," Kerry said at a joint news conference with the Israeli prime minister.
Netanyahu said stripping Syria of its chemical stockpile would make the region "a lot safer," although he was quick to draw parallels with the threat posed by a nuclear Iran.
"The world needs to ensure that radical regimes don't have weapons of mass destruction because, as we've learned once again in Syria, if rogue regimes have weapons of mass destruction they will use them," he said.
"What is true of...Syria is true of Iran."
Ya'alon too said that Iran's nuclear ambitions should be addressed, as well as the Syrian issue.
"In parallel, from our point of view, the world must display clear and uncompromising determination toward the extremist regime in Tehran and its advancing program to develop a military nuclear weapon," he said.
