Sure, I think we would have been involved in WWI no matter who was President, as for the later Taft he wanted to ignore the Soviet threat...
Why in the world do you believe America would have been involved in the Great War if the American President had simply maintained a real neutrality as even Wilsons first but sacked Sec of State Wm J Bryant demanded? And I must be missing something for in 1940 how could Taft have ignored the Soviet threat to a greater degree than giving them half of Europe and eventually throwing in China as Roosevelt did?
