This is a weird pet peeve of mine, and I'm guessing it's a British thing. The BBC puts a lot of little snippets in quotes. I know now that they're in quotes because they're quoting directly, but being American it looks shockingly disingenuous. Try this on for size:
I can almost imagine the Ayatollah sarcastically delivering this blurb, complete with rolling eyes and hand quotes. "'Unjust actions,' my foot," he's thinking. "Stupid American presidents, always butting in where they're not wanted." Except in Farsi, of course.
Maybe that's just me.
