@theROCmonster:
how does a yugoslavia factory prevent an egypt factory?
It does not.
IMHO there are two ways to deal with an Egypt factory.
1) Do Sea Lion. England just shot itself in the foot.
2) Invade Turkey and sweep into the Middle East which requires containing Russia, but not beating Russia.
If you do not do 1, I think you are best advised to do 2 simply for the fact that it stops them from getting complexes in C. Persia and Iraq (well they can get them, but they won’t be using them.) Meanwhile, you can put a major in Romania or some minors in Greece/Turkey to use against them and those are pretty safe. (Also kind of nice to have SZ 100 so you can swing transports into and out of the Black Sea threatening everything and being defended by 1 or 2 airbases and accompaning aircraft.)
