Any tips or strategys for this challenge? becuase so far its not a challenge, more of a nuase.
restarted it like 10 times.

do you mean the 'old' challenge 2 (now 'insane') or new challenge 2 ('crazy')?

The new chalange 2 :P

until you get a good feel for the AI, probably the best strategy i've come across is to just restart until you start in africa with no one else around for the first 4 turns. after that, expand through SA to NA -- being careful to attack both teams equally, you need them to fight each other -- and the world's then your oyster.

once you start to understand how the AI plays, you'll be able to do this challenge from most starting positions, although you'll still need a bit of luck to avoid getting sandwiched early on.
