"We are doing more to prevent future terrorism and terrorists by overthrowing these types of regimes"
The toppling of Saddam Hussein will not prevent future terrorism, if anything it will increase it.
More people hate the US now and with greater conviction than before, that means in all likelyhood more people will sign up to be terrorists.
"is their mandated poverty and oppression that breedz these terrorists from the hate that these regimes are so eager to deflect from themselves and onto the US"
Iraq was not a fundamentalist Islamic state and does not appear to have many connections with the terrorism that the West so fears.
"The gainz we've made are immeasurable as we may never know what we have prevented by denying these regimes their breeding groundz for US hatred and these ppl can focus on bettering their own futures for once."
They are immeasurable and they may well be negative. Fundamentalist states (Iraq was not one) are breeding grounds for US hatred, but then so are non-fundamentalist states like Pakistan, its not the state that matters, its the people. And attacking Islam, which is what the US is percieved to be doing by the 3rd world Muslims, is exactly what people like Bin Laden need to swell their ranks.
