I remember the protests. I am not surprised about Australia, it rings a few bells, but I honestly had no idea about Poland's involvement.
I remember the band Coldplay publicly criticizing, along with the usual protest from Bono. Also Madonna was married to Guy Ritchie and she was in the UK, she sent a message of support to the troops.
I liked Madonna that day, for I strongly believe that once troops are out there, they should get nothing but support, whether you support the cause or not. I can imagine how disheartening it would be to be over there and hearing the news that a bunch of musicians are not behind you. Soldiers don't make the political decisions but they do put their life on the line.
