Country star John Prine has launched a scathing attack on US President George W Bush, because he can't contain his anger over the war in Iraq.

The FAIR AND SQUARE hitmaker uses his song SOME HUMANS AIN'T HUMAN to take aim at the American leader, and cites Bush's nearby visit to his Ireland home as the final motivation to voice his distaste.

The lyrics read: "You're feeling freedom and the world's off your back/Some cowboy from Texas starts his own war in Iraq?"

He explains, "I have a place 45 minutes from Shannon. Bush made a visit to Shannon airport and they bought out the entire Irish army to keep the anti-war protesters at bay. I was already totally opposed to the Bush administration but not to the point where I felt like writing a song about it.

"He takes cheap shots, so I thought that one good turn deserved another."
