Russian President Vladimir Putin shook hands (and smiled) with President Obama on Thursday morning at the 2013 G-20 summit in St. Petersburg, Russia, where leaders of major countries were ostensibly meeting to discuss the stability of the global economy. The tense handshake — a controversial trope during Obama’s previous visits to Russia — underscored Putin’s interference with American foreign policy. Up until yesterday, Russia supplied arms to the Syrian government led by President Bashar al-Assad, and Putin has helped stanch a United Nations resolution to sanction military intervention in Syria, while demanding that such a resolution pass before Russia would support a U.S.-led strike.

What do presidents do when no one else can hear them? The same thing the rest of us do: complain about other people! Like on Monday, when President Obama and his French counterpart Nicolas Sarkozy were caught on microphone bitching about Israeli Prime Minister Benjamin Netanyahu.

Delightfully insane congresswoman Michele Bachmann has found more incontrovertible proof that Barack Obama is the Worst President of All Time: he is creating a so-called "global economy" where countries are "bound" to each other, economically. Who will stop this madman?

Tonight, Jon Stewart bounced back and forth between a few topics during his opening segment, from the United States' World Cup loss to Ghana, to the G20 Summit, to awkward beer bottle clanking moments with President Obama. Video inside.

The G-20 is when the world's economic leaders meet to talk trade. It's also prom to the international protest set. Anarchists, hippies, gutter punks: Everyone's invited, and it's your big chance to get photographed and get laid change the world.

Anarchist mobs protesting the G-20 summit smashed and looted stores in Toronto last weekend. One of their targets: American Apparel. A tipster sent us these photos of the demolished AA store—one more after the jump.

Toronto police have arrested over 500 people since yesterday morning in connection with G-20 protests that turned violent, with cop cars being burned and businesses in downtown Toronto vandalized.

So, the Nigerian man detained Sunday for locking himself in Northwest Flight 253's bathroom for an hour, two days after some other Nigerian tried to blow up the same flight? Definitely not a terrorist. Just a remarkably inopportune bathroom break.

Be careful what you twit for, because your 140 characters could land you in the slammer. Just ask Elliot Madison.

Did you know that our President and his wife are black? Well, they are, and Italian Prime Minister Silvio Berlusconi finds that endlessly humorous.

Protesters at the G20 meeting in Pittsburgh have been met my an overwhelming and thoroughly militarized police response. Here's a video gallery of some on-the-ground confrontations yesterday and overnight.

President Change is in London with a bunch of other world leaders at the G20 summit, trying to save the world! A reporter asked him if his meetings represented a "break" from Bush's foreign policy.

Oh hey did you hear that the Obamas went to England? They met the queen! And crappy presents notwithstanding, it was such a god damn regal moment that the world media, en masse, orgasmed.

All the world government big shots are meeting in London tomorrow for the G20. Really, they're much more worried about the hardtothemuthafuckincore protesters than the economy thing. Are UK protesters putting American protesters to shame?
