Sad isn't it? I do this all the time with fiction. Drives my dad nuts to hear me examining the logic of things other people made up.
But since we're already doing it; do you wander why Israelis are doing mercenary work at all? The write up seems to imply that Israel is doing well for itself, largely uneffected by the depression of other nations. They can afford to design and build nuclear powered tanks and transport them across the Atlantic so they must have several armor transporting airplanes or large transport boats (a quick peek
here leads me to believe they must have flown since I don't see anything approaching trans-oceanic armored transport). How much can the US be paying them when the rich people and economically strong sections of the country are the ones that rebelled to begin with?
Easier question: why on Earth did they sail one of
these 250 miles up what I have to assume was
this to help you fight a ground war?
How on Earth for that matter? Hell, an armored train probably would've worked better in Texas (that would have been bad ass).
