The problem is that our stupid government NEVER finish something they had started.
Look we could have destroyed Hizbullah in 2000, but Ehud Barak Yimach shmo fled away from Lebanon, abandoning everything behind.
And so everytime we flee, they just rearm and dig in stronger, so the next time is always harder and cost us with many Jewish soldiers.
So even if we attack now and start a war with them, the government will start an unilateral cease fire again.
