Nope I am not surprised at all.

In fact I wouldnt be surprised if his predessesors and or his replacment had done the same things in his place.

Despite the human inclination to place the onis of responsibility on a scapegoat, patsy or leader of prominace; even truely tyrantical ones. (for no world leader is capable of acting alone in reality):

Assigning blame on the recent economic decline is not something I believe can be squarely rested on any one single individual's shoulders, no matter how one paints the picture.

As for climate change? I believe it would be off topic to place an actual oppinion at this time other than to say the correlation would be spurious.
