Easiest argument to beat.. just ask them to define what is winning versus losing using historical context.
The dems define winning and losing day to day depending on what serves their purpose- which has nothing to do with the historical reality of what is defined as winning (or losing) wars.
You're asking a Lib to be logical?
According to the libs, we are losing every time an IED goes off.
Since we never hear of the other things happening, then there is never a sign of winning.
The absence of IEDs of course does not mean we are winning.
