To Missouri Patriot,
Really, Obama is a pedophile and a Muslim? Since when has being a Muslim been a crime? Also, show me the papers of arrests of Obama for some sort of child pornography.
Now, to answer the question.
Just because they have missiles doesn't mean our defenses can't stop theirs (I believe they are called patriot missiles). Also, we will have alternative energy before Iran becomes the leader of the world (although I doubt it will ever happen). Let us see what we can run cars on...
Wind power has always made sense to me. If you go 50mph and have some sort of device on your car that can harness that energy, presto there you go.
Water may be another option, but the exhaust would have to be water vapor, otherwise we would run out of water.
Ethanol, I'm not to keen on because, yes, we can renew it, but to have enough for our energy AND food consumption won't happen.
Lots of stuff can work, so yes, we will have some sort of energy source.
