Its not even a game actually. I mean you are comparing two forces of totally unequal magnitude. Israel probably has several hundreds of times a more military power, air power and naval power than the Palestinians. The Palestinians do not even have a remote chance of even touching Israel.
>>it's almost like they aren't even serious about killing people and using military force.
Your opponents have a fleet of most advanced air power backed by the biggest, most powerful and technically sophisticated army owned by a super power in the whole world. Coupled with this unmatched ground power. What you have is a gun, crude weapons and rockets.
Is this even a competition? Think of it more like practice sessions.
