<span>The correct answer is that the potential tourists from eastern states showed an increased interest in rail travel to visit the parks.
A lot of the people realized that traveling by rail there was safe and fast so the railroad industries figured out that they could cash in on it and started building more and more to bring more people there, even working with the government on it.</span>
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.
