This is interesting. In an article that describes frustration by the State Department over recent hawk-like commentary coming from presidential candidates, only the Republican is labeled a "radical."
First it was Barack Obama's talk of dialogue with dictators and invading Pakistan to kill Islamist militants, then it was Hillary Rodham Clinton refusing to rule out the use of nuclear weapons to that end. Now, the Democratic front-runners have been joined by radical Republican Rep. Tom Tancredo, who threatened to bomb Muslim holy sites to stop terror attacks.
I'd wager that threatening to invade Pakistan (a country with nuclear capabilities and whose U.S.-friendly prime minister is hanging on by his fingernails), and keeping the nuclear option on the table could be considered just as radical as bombing Mecca and Medina, the two holiest cities for Muslims. However, as these comments were made by Democrat frontrunners, they're not radical.
