This sort of talk confirms Iran's view of the recent protests and undercuts Obama's attempts to portray the US as neutral. Of course we already know that funds have been allocated to do precisely the sort of things that Newt commends. If any sabotage occurs Iran will know who to blame and Gingrich provides the smoking gun evidence!

US politician urges Iran 'sabotage'
The former speaker of the US House of Representatives has said that the US should "sabotage" Iran's oil and gas infrastructure as part of its efforts to bring down the government.
In an interview with Al Jazeera's Avi Lewis for the Fault Lines programme, Republican Newt Gingrich said targeting Iran's refinery would spark an economic crisis that would destabilise the government in Tehran.
He said the US should "use covert operations … to create a gasoline-led crisis to try and replace the regime".
"I think we have a vested interest, the world has a vested interest, in a responsible Iranian government, just as we have a vested interest in a responsible North Korean government," he said.
