Most in the Republican base don't even know they have a Doctrine. To put it simply, the Bush/Republican Doctrine is to attack and level a country you think might one day, in the far future, threaten the US. An example of the Bush/Republican Doctrine being applied? Iraq. An example of Republicans wanting to apply the Bush/Republican Doctrine? Bomb bomb bomb....bomb bomb Iran. Why this Doctrine didn't work in Iraq? George Bush tricked the US into invading Iraq. There was no "ownership" by the people. What did they do? They rioted and looted their own country. They attacked the Christians living there since the time of Christ reducing the population by up to a million. They put their women in Burkas. They put up a monument to the man who threw shoes at our president. Maybe it was a thanks, "Here, I love you so much, take my shoes", others think it was a deadly insult. The people simply were not "invested" because this wasn't a "revolution". Obama in Libya supported those in revolt. They are invested. Very little looting has been reported. The US is not responsible for nation building because we didn't tear down that nation. The people in Libya are invested in their own future. Overseas, Obama's actions are being described as "thoughtful" and "wise". Right wingers call him "boy" and "manchild". Of course, I'm sure there is nothing "racial" in those comments. The reason Obama has been much more successful overseas than domestically is because it's much easier for the Republican Party to block his actions domestically. I suspect he would achieve the same level of success if Republicans worked with him instead of demanding he fail, or at least get out of the way. Of course, that won't happen. Because they want him to "fail".
