The recently-deceased American political scientist who asserted that post-Cold War international conflict would be rooted in a clash of civilizations is Francis F`u kuyama.
In 1992, he published a book called The End of History and the Last Man, where he argued that the world had been moving towards a Western liberal democratic future and that with the end of the Cold War, this evolution had reached its inevitable end.
