I moved to Iowa in Jan 2000 and moved back to Canada Dec 23 , 2004. I was there for almost 5 years.
When people learned I was a former soldier , they always asked if I was US ARMY, then they were shocked to learn I was Canadian Army. Some were more shocked to learn Canada had any sort of a miliary, thought it was the RCMP that was the army group. I always explained the RCMP was like the FBI, the national police force etc.
When 9/11 happened I was given a hardtime because they all thought the terrorist came thru Canada. When the war was started, they were mad because Canada would not support the USA in the war in Iraq , they never reported much in the States about Canadians being on the line in Afghanistan. Even after the bombing of the troops by mistake. From what I saw on tv and heard in public, it the US forces and British Forces. Perhaps because we did not send troops to Iraq , our troops in Afghanistan did not mean anything till the reports of the Canadian Snipers saving lives thru amazing shots and great action reports, did most Americans I know even knew we were there.
I know there was some ANTI - Canadian feelings in the USA, it is not the everyday feeling but it is there.
