Gotta keep your eyes on the biblical data.
For many years now, some friends have argued that the AC must come from here or there because influential eschatologists had previously drawn such conclusions based on geo-political factors applicable during the last 50 years. Unfortunately, some of those important geo-political factors are lately descendant while other new ones are ascendant (for example, the descendancy/decline in importance of the EU and the ascendancy of Islam and the Islamic world).
I tend to agree with eschatologists who say that Prophetic Scripture is alive and that the key to understanding it is prayer and fasting combined with a keen and discerning eye toward present developments.
Not saying that Obama is the AC or that he isn't. But I am saying that the world seems to be entering an End Times quickening. It certainly seems like Israel is being increasingly threatened by those menacing forces which surround her and that we are increasingly aware that those forces (Islamic, Anti-Christian forces) are supported by Obama.
BTW, it is interesting to note that as far back as 2007 (prior to his AIPAC speech in March 2007) Obama had proclaimed himself a "friend of Israel." More than three years later, it is becoming commonly accepted that he was lying just to win the Jewish vote. His encouragement of Mubarak to step aside to create a vacuum for the MB (knowing full-well that the MB has called for open war on Israel) seems to represent a public shift in his attitude toward Israel.
Just saying.;-)
