What did all dictators have in common leading up to world war 2?

An ultranationalist ideology that came to be known as Fascism because the first example of it was set by Mussolini in Italy under that name.

How did the lend lease act serve as a preaches or to the United States entering world war 2?

The land lease was a way for the US to enter the war indirectly by helping the Soviet Union in its offensive against Nazi Germany. The US only provided partial military and economic aid, although it would eventually become fully involved in the war.

Was the bombing of Pearl Harbor inevitable? Do you think it could been prevented?

It could probably have been prevented with better military intelligence. The US should have been very suspicious of Japan, even if Japan had not showed any explicit intention to enter a war with the US by then.
