Loosing afew of "our" soldiers to save many sivilians in the future you mean?
Tricky question to answer i think, but is there any gurantee that we actually save any in the future?
Will this attack on Iraq stop future terrorist attacks on the US or any other nation?. or will it enhance the resolve and hate that many organisations/individuals and countries have agains us?
This war is a gamble and i dont think its the correct way to fight terrorism and or make the world a safer place for all.
We will not know the outcome of this thing for many years ...if ever.
Without the UN supporting this war, it will without a doubt be a huge propaganda victory for all the "groups" that already has a grudge against us and in that respect this war has already been lost.
