Both sides kill civillians, it's not right but that's how it seems to go. Any war has many civillian deaths (50 000 so far in Iraq) so, I can't ever see myself supporting a terrorist group such as the HizbAllah.
Saudi's wouldn't have shit if they didn't have oil. If they didn't have Oil they'd get nothing and no influence.
but you're right on the second part. If that happens it's a definate world war unless Israel just disbands and it's people go to other western countries.
