Opinion of Woodrow Wilson

[True Federalist (진정한 연방 주의자)]

He wasn't undecided about World War I.  He actively took steps to prop up the Entente Powers as early as 1915.  He was definitely not the paragon of neutrality his supporters like to claim.

the good things he did was the income tax, direct election of senators and women suffrage.

You do realize that none of those were due to Wilson.  Leaving aside the fact that Presidents can do nothing except make use of the bully pulpit to get amendments passed, he didn't even do that much.  The 16th and 17th Amendments were sent to the States for ratification while Taft was President. New Jersey (where Wilson had been governor) never ratified the 16th and only ratified the 17th after Wilson had resigned as Governor to become President.  (Not that Governors have anything more to do with passing amendments than do Presidents, but you'd think that if he were staunchly behind them, he'd have have gotten New Jersey to ratify them before he resigned on March 1.)

On Women's suffrage the evidence is quite clear that he had to be dragged into supporting it once it became the politically popular thing to do.

It wasn't just American troops. but American war material that let the Entente Powers win World War I.  Had Wilson chosen to not follow Treasury Secretary McAdoo's advice in 1915 and not allow the Entente Powers to take out loans in the United States instead of having to pay specie for the war material they bought here, the Entente Powers would have not have been able to buy as much war material in America as they did.  It is entirely possible that the German offensive on the western front would have succeeded.  Certainly the Germans would have had fewer reasons to resume unrestricted submarine warfare in 1917 had the United States not abandoned strict neutrality in 1915 to become the Entente's munition factory.

It was Wilson's tilt towards the Entente that caused Bryan to resign in June 1915 as Secretary of State.
