"would it be ok if iraq sent missiles into israel again? after all they are still at war, iraq refusing to sign a peace agreement in 1948 after its invasion of both Palestine and Israel"
No it would not be OK. Resolution 687, which Iraq agreed to as a condition of the cease-fire of the Gulf War, prohibits them from having or using ballistic missiles of greater than 150 km range. Israel is farther away than that. I don't know whether Iraq has cruise missiles, though.
