Think about the consequences of a Barack Obama victory in November...
The United States President
The British Prime Minister
The Australian Prime Minister
The most left wing US President ever (in fact, a radical leftist) + a populist, spineless British PM + a populist, incompetent Australian PM = bad news for the world.
This triumvirate would be Kim Il Jong's and Ahmadinejad's and Assad's and Hezbollah's and Hamas' and Al Qaeda's dream come true.
The UN would remain feckless. Nobody would do anything about Mugabe or any of the other miserable dictators in the world.
The English Speaking World leads, the rest follow.
Would there have ever been a weaker combination of leaders of their respective countries than these three? If so then I can't name them.
