Now what?

Here’s a not-so-hypothetical situation submitted for your consideration.

–In May 2000 Israel withdraws all of its forces from southern Lebanon.

–In June 2000 the United Nations certifies that Israel has complied with Security Council Resolution 425, calling for the withdrawal of Israeli forces from Lebanon.

–In July 2006, Hezbollah launches dozens of Katyusha rockets and mortar bombs from Lebanon at the Israeli town of Shlomi and at Israeli outposts in the Shebaa Farms area. Hezbollah forces cross the UN-recognized border from Lebanon into Israel, kill three Israeli soldiers, kidnap two others and take them back into Lebanon.

What should Israel do now?
