Why aren't we propping up the Lebanese Army?

I was watching CNN a few minutes ago and one of the correspondents was referring to the dominance of Hezbollah being a result of the Lebanese Army being so weak. Well, then why aren't we propping them up? By we, I mean those countries that have an interest in Lebanon being a functioning democracy and not a bombed out hell hole. If Hezbollah was such a grave concern, then why aren't we shipping munitions and military aid to Lebanon instead of bombs to Israel? Sure, maybe they can't afford them right now, but call it aid. Ship it to them on credit or as a donation. It's either in our interests to support Lebanon's government and national armed forces or it's not.

I just really hate seeing these lame justifications for what's going on.

This was an aggressive action taken out by Israel, which is escalating and no one can do a thing about it. Except maybe to prop up the Lebanese armed forces. But then that wouldn't allow Syria and Iran to slip into the fray (which they are not stuid enough to do).
