First of all it is not an illegal war. That is your opinion. If it were illegal you as even a civilian would have the power to arrest a soldier who has been there. Are you going to??
Secondly, if you are referring indirectly to WOMD's and the fact they have not be found, so what? Politicians lie all the time, that's what they do. The true facts are thabkfully kept with in the secret services.
Thirdly, the oil flow is worth fighting for if WOMDs were a complete hoax. People who moan about the war are often the first to moan about increased EVERYTHING due to oil prices. And I mean everything.
Fourthly, soldiers can not choose where to fight. Yes they choose to sign up, but not where they are sent. Do you oppose the millions of hours our armed services do on peace enyoys, illegal drug tarfficking, fighting drug lords atr sea, rescue services all round the world, protecting the crown and its subjects from filth like the Argies who did infact illegally invade The Falklands.
If you do not support our boys, you do not support the country. And if you don't support the country, then you have no place in society and should bu66er off to a marxist loving kibbutz helping single parent lesbian mothers save the rainforest whilst smoking some weird old tobacco from a muslim made hubbly bubbly.
