Remember the stories from the right of how Bush had single-handedly conquered his substance abuse problem? There was no need to worry he might fall off the wagon because he found Jesus.
Remember how as New Orleans was drowning Bush was at a fund raiser, struming a guitar?
Now, as the world heads towards WWIII, here we see Bush, looking soused. And what's that bottle in front of you Mr. President? Looks like a beer to me. And it looks like he's had more than one.
Once one admits to a substance abuse problem, they are admitting that the substance is more powerful than their will. They can never use the substance again, as it will lead them back down that road again.
This picture thereby gives creedence to the rumors that Bush has been drinking again.
