True enough, though Argentina had weeks in which it could have negotiated. Instead, they just ignored UN Security Council Resolution 502 which among other things demanded the withdrawal of all Argentine troops from the Falklands, pending negotiations through the UN. Sadly for all the young Argentine conscripts, most of whom didn't want to be there anyway, Galtieri wasn't having anything to do with UN resolutions.
I agree.
As, no doubt ,you will agree with me that Mr Tony correctly invaded Iraq.
Edit: the only thing wrong with the Falklands war was it started weeks late: the silly old bitch refused to take action until the 25th hour, because she though the soppy Argie fascist was her ally in the war against communism
