Have you considered reading a WWII history book? That was a far more impressive and substantial mobilization to multiple countries spanning multiple continents which was done without the benefit of software. It took more than a few months largely because they had to manufacture equipment and recruit/train personnel from scratch.

Either you're doing one epic troll or you're displaying a staggering ignorance of the ability for militaries going back to the time of the Roman Empire to do significant mobilizations.
