I don't want to criticize everything the man does, but Europeans are not amused that the American President - who wasn't able to attend the funeral of the Polish President for completely valid reasons - nonetheless took advantage of the occasion to play golf.
And I don't want to criticize everything the media does - but they suffered ludicrous meltdowns even when Bush wasn't playing golf! (So far, Obama has played golf 8 times more often than Bush - which is utterly fine by me, but I'm waiting for the media outrage.)
Clinton and Biden, at least, took time to visit the Polish embassy.
While a petty matter in the grand scope, such intentional slights or shows of discard for foreign allies has becoming widely-observed as ... well, par for the course with Obama. Poland, a staunch ally which all of Eastern Europe feels was betrayed by Obama following his revocation of a missile shield as a concession to Russia, is the last country in the world which should be shown the cold shoulder.
If only they were a Middle-Eastern dictatorship, a Latin American junta or a de facto soviet menace, surely then, they are well aware, they would be treated with respect.
