When i play step 1 of the paradise campaign i lose if i don't invade the enemy country for a while or if my initial invasion wave is destroyed. Even if my transport's cargo hold is filled with tanks waiting to invade i lose the scenario if my initial invasion fails. What are the defeat conditions for the F.N.U.?

Well, According to the idea F.N.U. should NOT let the Phantom League have control over this country even for a single turn. Ph.L. has control initially, but this must be interrupted by F.N.U. immediately - during F.N.U.'s first turn.

Threfore, the F.N.U loses if i follow any other strategy? No other strategy is acceptable?
