Level 2 war (Golden Rainbow)

why is it so much harder than level 1.
I started one and my air units got creamed
off AA did nothing but die and don't know what killed em
I guess I will have to get more workers and get 2 fully upgraded attack fighter squadron
air units were 180 weapon quality
15000 casualities me 700 them

fight war of attrition
you have moar ppl than them.
dont use off AA, try guerilla hit and run tactics
use attack and bombing wing loaded with lots of ammo to take down air d
upgrade your units, except for suicide bombers
even at, say 1500:700 casualties, you should have killed their entire population by the end of the war
