Terrorism Vs. War

I know this may sound odd, but am I the only one that does not see a difference between war and terrorism? I mean, there are good and bad 'wars', and most people view 'terrorism' as bad. That's not what im arguing. The objective of both (war and terrorism) is to encroach on the enemy's safety, enough so to where they would surrender so you could achieve whatever objective you set out. So, as evil as some guy that blows himself up along with a bunch of innocent people may seem, to me it just seems as if its a matter of resources that causes a distinction, and wealthier militaries have the resources to accomplish their goals without resorting to suicide bombings, while the factional warlords do not. So you cant justify war because of its formality (rules of engagement), war is terrorism, no matter how good the objective, and terrorism is war, no matter the evil behind it.
