Yes, I agree this appears very petty and low. But let us remember, the citizens of the USA have done similar things. Looking at the bigger picture, not everyone agreed with the US on the war against Iraq issue. The French were just the most vocal of those opposed. The US started the mudslinging with freedom fries and "We hate France" t-shirts.
And FYI, God has blessed America, land of the rich. Who do they think they are to tell God to bless their country?
