Your point is invalid, you're not in a position to nuke anyone. Your troops should be restricted like the German troops were after the world war two, cause you were doing lots of shit in the last decades. Tell me, where do you get that christians were not equal to muslims in those countries? As just a few seconds tip, read the article the guy above posted: http://www.pbs.org/newshour/rundown/mid-easts-christians-intro/
So, if you say that christians have no rights in those countries, you should have something to back that up, and do you? And not to mention countries like Lebanon, Turkey, Jordan, which are democratic and predominantly muslims... And christians are not discriminated.
Second, answer me than, why is your government allied to Saudi Arabia? Why does your government arm islamists, and in Syria, islamists who actually fight against the regime which is supported by the majority of christian population in Syria. So not that your government works to help christians, it actually works against them. I mean, I'm not saying your government intentionally does that, but it's just a proof how your government gives a shit about christians or any kind of injustice, but it cares only about it's perverted agenda of gaining more power and dominating middle east.
And another question, who are you to decide which country gets to behave in which way? Who are you to decide who gets nuked? If you wanna nuke the criminals you should nuke yourself first. In any case you have no business mingling in other countries, so next time when you wanna 'defend yourself', you should do it on your own ground for a change.
