@shadowhawk that seems logic but in the recent games germany invests 40 of its 55 average income (when they take leningrad) into land units to slowly march on moscow. The rest they buy a carrier, DD and sub on G1 and a sub and bomber every other turn so there is quite some built up.
It´s feasible to go there but yet again from there on, if you move to norway for exemple your follow-up forces in Gibraltar are vulnerable if you send your protection along with your big tpt fleet.
Maybe the Sahara expres can provide some early forces and pressure While you built up your Gibraltar fleet.
