well, just getting 1 rocket off is super expensive your would need thousands of rockets to get the army there. people would lose there homes from the taxes.
if taxes made people lose their homes then people would alot of people wouldn't have a home now were not raising the taxes besides we obnly need 1 spaceship to carry the army
it would take months just to get them there using 1 ship the u.s has more than 30,000 soldiers and usually only 3 people fit in a ship which would take almost 2 months to get back to earth.
