The term "cake walk" for dead and maimed American soldiers is the issue, not comparisons with previous wars. If I give you some email addresses of mothers, fathers, sisters, brothers, spouses and children of the dead, would you be so kind as to write them and tell them their loved-ones died in a "cake walk?"
If we told them their children died in a winning conflict, in one we won in a cake-walk, they'd be proud of how their children fought. Yes.
We've become so 'politically correct' that I can't even point out this is an easy war, compared to what a 'bad war' is like?
Every American soldier's death is bad.
That does not make the battles they fought in a disaster.
