Criticize or defend each of the u. s. actions surrounding world war ii listed below:
◦u. s aid to china
◦lend-lease act

I would support US aid to China, as i helped both Americans and Chinese.

Japan couldn't focus entirely on eastern (Pacific) front, it also had to fight against Chinese guerillas, who were a bigger threat thanks to american support.
From Chinese perspective, thanks to US help they were able to better resist invading army.

As for Lend-lease, I would also support this act, as it helped USSR in earlier parts of the war, when red army was significantly underequipped. In later part of the war Lend Lease helped  in regards to logistics, and since the distances on eastern front were huge it has sped up russian progress a lot. Consequently Nazi war crimes were ended more rapidly.
