Are you saying, in the hypothetical, that you would rather be ruled over by a cruel muslim than a wise and moral christian?
Muslims can't ever be ruled over by non-muslims no matter how moral or wise they are. Muslim country can only have a Muslim ruler and is the rule of Islam. As for a cruel ruler, well the prophet said this
"Help your brother, whether he is an oppressor or he is an oppressed one. People asked, "O Allah's Apostle! It is all right to help him if he is oppressed, but how should we help him if he is an oppressor?" The Prophet said, "By preventing him from oppressing others."
Muslims want good leaders not oppressors. The oppessors are being protected by US because without them US oil interest will be in a limbo. US put shah in power, he was a geocidial lunatic, look at what ppl did to him. They revolted in a revolution and forced him out of power. Look at what mushraf is facing right now, they want him out. There's others like egypt's president and royal family of saudi that are safe by US otherwise do you think they would still be in power?
Also, you said
For myself, I would rather live in a democracy with a muslim leader than live in a police state run by a christian.
You should look at around on this thread, see how many christians here want a war rather then be ruled over by Muslims, even if those are american converts only. As for you, you are already living in a police state, it's 1/2 there and 1/2 is left before it becomes total police state. How many more of your liberty rights will you give up to bush?
Many Muslim countries have shown an inability to rule themselves. The truth is, the U.S. must look after it's national interests. If a Muslim country such as Iraq or Afganistan is a threat to U.S. national security, then it is morally right to invade and occupy that country. If muslim nations are unable to live at peace with the rest of the world, then they cannot be allowed to rule themselves. I apply the same thing to any country, not just muslim ones.
As for what gives the U.S. the right. Two things. First, every country has a right to defend itself and it's legitimate national interests. Secondly, as the most powerful country in the world, the U.S. has a responsibility to try to create a better world.
Many Muslims countries continue live well and enjoy it (malaysia to name one) and these only countries that US has not meddled in. US does not have a puppet regime in place nor protects the evil dictators and their thrones.
US national interest is oil, it wants to keep US friendly regimes in power for that and if anyone doesn't become US friendly (saddam) then they are shown as hitler in the media and faulty intelligence is made to look real in their propaganda and then war is wage. And you US national security was not threatened by iraq or afghan, not from across the world. Do you honestly think they can attack US from all the way over there. As for 9-11, afghan had nothing to do with it except not turning over OBL without proof, which US failed to support. It is morally right for all those Muslims to fight US in any muslim country US presense and occupation is, it is their right by land, by life and by religion to defend themselves.
Every country has a right defend itself, but US has was not in any danger and 9-11, well the verdict is still out as to who the real cuplrit was on that. As for US creating a better world, only world it's creating is a dangerous world. Many countries, even US closest allies, have made statements that it's "war on terror" has made it a more dangerous world. US is far from creating it better world, it's rather the opposite. Do you think most Muslims feel safe in non-muslim countries now with anyone being able to be arrested on somenoe's mere "suspicion"? And how safe do you think americans feel in return when they go to muslim nations cuase of whattheir leaders are doing?
