Appeasement will not work. Iran is determined to have a nuclear weapon and this is just a ploy to gain time. Western leaders are unbelievers and cannot discern truth for the spirit of God is not in them.
I would go further and say, that while there are many many politicians who are now working in the darkness of evil, there are a few, Reid, Pelosi and Obama who are openly doing the bidding for the Evil One. There is no stopping their evil ways from this point forward.
When I pray for world leaders, and the leaders of the U.S., I've been specifically praying for those who profess to be members of the body of Christ. I shudder to think what will become of them.
