Question

what did the u.s. and britain promise in the atlantic charter? that britain would share war planning with the u.s. that the u.s. would lead the allied war effort that the world would be better after the war that the u.s. and britain would always be allies

Explanation:

The Atlantic Charter (1941) was a joint declaration by the US and Britain. Among the options, the idea of a better post - war world (focus on principles like self - determination, economic cooperation, etc. to improve the world after the war) aligns with the charter's goals. The other options: sharing war planning was more of a wartime cooperation aspect but not the main promise; the US leading the Allied effort is incorrect as it was a joint effort; and the “always be allies” is not a core promise of the charter.

Answer:

the option "that the world would be better after the war" (the second option in the list, with the text "that the world would be better after the war")
