At first, the allies welcomed the overthrow of russia’s tsar in 1917 because

a. it allowed germany to concentrate its forces on the western front.
b. the tsar had recently made a secret alliance with germany.
c. they believed the spread of communism would end the war.
d. they hoped russia would become more democratic and a stronger ally.

the answer is c my brotha. c.   formed an alliance with the soviet union.

it was certainly a debatable decision, mainly because it was based primarily on political - and not on legal or social - views. since the congress at that time was led by members of the republican party, and the territory that the tribes wanted to turn into an exclusively indian state was predominantly democratic, the proposal (as expressed in the constitution) did not succeed, but the constitution itself proved to be of crucial importance in the creation of the state of oklahoma, and, most importantly, it guaranteed the involvement of representatives of the indian tribes in the government of the future joint state.  

as a member of congress, i would have voted to ratify the constitution, or at least to have it tabled. ignoring it was an interested and partial decision.
