"Thanks Obama" is a long running joke, tracing back to when people who were anti-Obama used it as a slogan, ironically thanking him for things they blamed him for. Due to propaganda and whatnot, these things were often mostly or entirely unrelated to Obama's actions and influence, so much so that it gave birth to the joke of saying "Thanks, Obama"when literally anything bad happens. The joke's popularity took a huge nose dive when Obama himself referenced it, as is often the case, but it's still around.

This one is particularly fresh since its in Japanese with a presumably Japanese person in the picture, making it even more absurd than usual.

And that's the full /r/outoftheloop version, sorry for ruining the joke by explaining it, thanks Obama.
