Wilson got the US into WWI because JP Morgan had lent lots of money to the Brits and the war in the trenches by 1916 looked like it would fo on forever, consuming every resource, until the Brits would not be able to pay JP back. Wilson understood that Morgan had saved the US from one terrible Panic almost singlehandedly, so great was his wealth, and was convinced that if Morgan and his bank went bust, the US would have a disaster on its hands.
It is true that Wilson was the first Southerner elected to the presidency since the Civil War. He managed to get in by also being the President of Princeton University and then the Governor of New Jersey. Wilson may have been a racist, but that was not why he got the US into WWI. In 912, there were few White people who were not racists. I think TR invited Booker T and GW Carver to the White House once, but he also stated that he didn't think most Black people were much good at intellectual pursuits.
It was a major mistake, in my opinion. It led to the Treaty of Versailles, in which Wilson was one of the good guys, ot at least the better ones. The League of Nations was a good idea of Wilson's as well.
But Barak Obama is a century away from Wilson's time, and there is no relationship whatever. Obama inherits a nation involved in two wars, and until at least one is concluded, there are not the troops or the money to have another one. They also must be running out of money, as Iraq alone is costing 10 billion a month.
Republicans brought us an untenable and disastrous deployment to Lebanon, followed by an invasion of Grenada. Then there was a war with Panama. Worst was the First Gulf War, provoked by Olebush, and its less competent rerum, clearly begun my Juniorbush. War is what Republicans DO.
Yes, I am aware of Bosnia and Kosovo, but at least these were done in concert with NATO and allies, and brought fae fewer casualties.
