Over the last dozen years, Israel has often been involved in a round robin of military conflicts: Lebanon, Gaza, West Bank, Gaza, Lebanon, Gaza, secret missions into Syria. It seems that now the focus is back on Lebanon after December 08's counter terrorism campaign in Gaza.
Whenever Israel has launched a military campaign into Lebanon to strike back against Hezbollah, the world media condemns Israel for victimizing the Lebanese. Since Hezbollah, a notorious terrorist organization, is firmly entrenched in the Lebanese government and has tremendous influence over the Lebanese military, and despite any Western leaning ideals possessed by other Lebanese political factions, at the end of the day Hezbollah and thereby Lebanon is a valid target of the Israel Defense Forces.
In the Middle East, might makes right, especially in Lebanon regardless of what party sits at the top of the government. Hezbollah is armed with thousands of rockets and personnel and flushed with millions of dollars not including additional support it receives from Iran and Syria. Time will tell if Israel will once again preemptively strike in Lebanon to quell the growing military power exhibited by Hezbollah.
