Althought the lusitania was sunk i 1915, and it angered many americans, the government refused to go to war. why do you think the country remained out of the war for two more years?

The United States entered the war because of the Germans' decision to resume the policy of unrestricted submarine warfare, and the so-called "Zimmerman telegram," intercepted by the British, in which Germany floated the idea of an alliance with Mexico. Unrestricted submarine warfare, a desperate effort to counter the British blockade of Germany, would lead to the sinking of American merchant ships heading for England, and had been employed by the Germans before. They abandoned it in the face of US pressure earlier in the war. Its resumption was enough to cause Woodrow Wilson to renounce his stated position of neutrality, as his war speech to Congress demonstrates:

The new policy has swept every restriction aside. Vessels of every kind, whatever their flag, their character, their cargo, their destination, their errand, have been ruthlessly sent to the bottom without warning and without thought of help...

a. competition with other nations.

hey, did you get this? could you me out?
