WI Roosevelt was a Republican in 1912?

Assuming that the republican party kept their party in tact and united behind Roosevelt, and assuming they won, what would have happened? Would the United States have entered WWI sooner?
 
Perhaps if TR stayed out of it himself and Bob LaFollette Sr. became the GOP nominee instead? Otherwise, have the Dems nominate Champ Clark, which leaves the GOP most of the centre, all of the left and some of the right. ;)

Teddy Roosevelt doesn’t stage a walkout at the Republican Convention in Chicago and eventually wins the nomination of the Republican Party.

John Schrank’s assassination attempt on October 14, 1912 goes ahead as before and news of Roosevelt delivering his speech for ninety minutes with blood seeping from his chest causes a sensation.

Teddy wins the Presidential Election in November.

World War One kicks off as usual in August of 1914 and Germany declares unrestricted U-boat attacks in February 1915, again as usual.

Roosevelt issues warnings and begins improving the United States woeful military position.

The Lusitania’s sinking is all the justification Roosevelt needs. In his speech to a Joint Session of Congress he declares that “The Seventh of May 1915 is a date which will live in infamy”.

The United States enters World War One on May 9th, 1915.

US forces start arriving in Europe in August that year and begin to bolster the Western Front. However, they do not launch any offensives, seeing frontal assaults on that front as totally fruitless.

Instead landings are made on the Adriatic Coast against Austria – Hungry and an Anglo American army pushes up from Suez into Palestine and takes Damascus. The entire Arabian Peninsula falls to the Allies in 1916.

The Central Powers position begins to seriously suffer in 1916.

Secret negotiations begin in Sweden for a Ceasefire based on Status Quo Ante Bellum…

In 1917 Den Hague hosts the Convention for the Future Peace of Europe and the World.
 
As said if WWI happens (very likely) the US will enter much sooner thus causing an earlier and clear Allied victory.

The follow up questions are:
What the peace would look like? particularly for Germany and Austria Hungary (which is likely to collapse anyway).
Would Teddy run again in 1916? If he does would he win?
Has the Great Depression been butterflied away? a WWII?

What happens to the Middle East? Since the scenario above would radically alter it.

Butterflies across the world?
 
Although Roosevelt may have wanted war with Germany as with his nephew later he would have had problems getting congress to declare war even after the Lusitania and the Baralongh affair may have temporarily halted him after the Lusitania. It is also possible that Germany would have restricted submarine warfare knowing that Roosevelt was prepared to go to war. Rossevelt might have tried to provoke an incident with the U-boats by aggressive neutrality patrols and would probably have got involved in the war earlier than Wilson but probably not as early as 1916
 
All of the above overlook the enormous prestige TR enjoyed in the chancelleries of Europe. He may well have seen an opportunity similar to that he seized in 1905 and offered the would-be belligerents his services as arbitrator/mediator in mid-to-late July 1914. Given that the Kaiser seized at straws to avert conflict at the eleventh hour in OTL, given that the Kaiser referred to TR as "my friend Roosevelt", and given the rather chummy relations TR had with the British, it seems to me like negotiation may well have ensued, beginning sometime in August 1914--which may well have averted the war entirely.
 
tr assuming that he became President again after the 1912 election might very well have been willing to assume the roll of peacemaker. He might very well have been the one man that could have brokered a peace.

Teddy Roosevelt would have had a much easier time getting the United States into World War 1 then FDR did in WW2. Woodrow Wilson was determined to keep the United States out of WW1 and only entered after prolonged provocations by Germany.
Had he lived long enough to be at Versailles his strategic vision would have allowed him to see the massive flaws in the Peace Treaty.
