The word impossible does not exist for me. I've got a lot of signal flags in my flag bag, but there is not a white one in there. I am going to keep fighting until the day I die - and might keep on fighting afterward ... depends on where I am.
The Iranians don't intimidate! They're like the Vietnamese and the Iraqis. You want to start a war with them? They'll still be fighting in fifty years!
The worst thing you can do if you want to start a fight is to use derogatory terminology.
