The fact is, Obama uses the word terrorism a lot, as you can see if you'd just take the time to read some of the transcripts on the White House Website. In fact, his last radio address uses the word or some variant of it six times in four minutes and fifty seconds. The page on the website that addresses Homeland Security uses the word terrorism four times. A search for the word "terrorism" on the Whitehouse.gov site turns up nine pages of hits.
As for the lie that 'he doesn't even call it a war anymore" , here's a graf from the same address:
On that day I also made it very clear-our nation is at war against a far-reaching network of violence and hatred, and that we will do whatever it takes to defeat them and defend our country, even as we uphold the values that have always distinguished America among nations.
How much more often would the President have to use the word to satisfy people like Krauthammer? The answer is: none. They'll just keep lying.
So arm yourselves with the facts for the next time some wingnut starts spreading the lie that "Obama doesn't even call it terrorism any more!"
