Iran already has ample items to defend its territories
a) Huge Man Power
b) F14 Tom Cats with long range radars , with Missiles that are Long Range
c) 100 new fighters with new avionics and airframes
d) Local Production of S-200 + which has a kill ratio of 85%
e) Countless Missiles for offensive duties (Irani fighters don't even need to leave their own airspace)
f) UAV (Conventional and Stealth that even spied on American carriers)
g) Unlimited Attack Helicopters (Cobras) so ground invasion of any kind will result in heavy casualties for enemies
h) Unconventional flying boats (which can fire anti ship missiles) radars do not pick these low flying ships
