Do some math man 170K out of 330 million even if you were to be extremely generous and take the total of people in active duty 1.3-1.5 million we don't even crack the top 10 for per capita service. Our armed forces are only able to recruit because as you know the standards are extremely low most recruits would not pass if they kept their standards high.
Again you think people are going to pick up weapons to fight their neighbors when you can't even get most Americans to care enough to vote or serve.
