It's fun with words time!The Republican party often will expess the importance about bringing democracy to totalitarian governments, yet they will adamantly insist that the U.S. is a republic and not a democracy.
A Republican just boils down to this - your national leader is not called a king or queen.
So the US is a Republic. So was Stalinist Russia. So is the People's Republic of China. So is President Mahmoud Ahm-a-dinnerjacket of Iran.
Now King Abdullah of Saudi Arabia could not claim his country is a Republic.
The UK is sort of a quasi-republic. Technically, I suppose the Queen could veto a Parliament bill, but that would quickly lead to the Queen being tossed out on her butt.
Labels in politics tend to be confusing if you look beyond the perjorative. Example - Look at that Liberal there riding in the front of the bus! They think they own the world!
