Simple. If you mean military/attack target, not fighting other's wars brings our troops home to protect our country.
If you mean from a financial/business point of attack, not so easy.
But there is something wrong when we have a TON of foreign cars in the US and hardly any Ford, Chevy or Dodge throughout the world.
There's a lot of issues. Foreign trade laws/tarrifs, bad business practices (bailing out banks and the auto makers, the UAW, etc.)
I wish there was an easy button for that. There isn't. But clearly what is in place isn't working.
