All corporations' desire is to acquire market share. Ford is trying to take it from GM.....GM from Chrysler.....Chrysler from Nissan.....Nissan from Toyota.....etc.
You make it sound like Nissan is a malevolent foreign invader. They're not. They are a foreign investor, because they believe by making a truck here (in the States) they can make a profit. If they take the dollars back to Japan (which they don't, since you can't buy anything there with them), so what? They traded trucks for slips of paper of diminishing value.
The Japanese government's monetary policy doesn't affect the profitability of the Titan in any way. Nissan isn't exporting trucks from Japan to here, nor are they exporting from here to there. Ford isn't doing it, either. There's no market for a big truck there, nor here for a truck that costs a fortune to ship across an ocean.
If anything, the Titan represents an Americanized-Nissan doing business in America, as an American corporation, by hiring Americans to produce a product for sale to other Americans.
Do you really believe they are stealing something from you or others? If so, what?
