We're all !equal

Today I’ve found funny picture where present president of USA Barrack Obama says (my own translation):
“In the moment of such tragedy and such pain we all are Polish”

Although I know what he meant, comment under the picture is still quite funny. Here is what it says:
“We’re all Polish… but not all have visas”
It’s old subject about Poland having big problem with US visas. I understand my nationals as US has no-visas traffic with smaller countries which sent a lot less army to help the US forces fight with terror. It reminds me words of one Bloodhound Gang’s song “We’re all equal unless you’re Canadian (Polish)":)
