A reason the Neutrality Acts were revised to allow cash-and-carry in the 1930s was that fascism was gaining ground in Europe.

Explanation:

Neutrality Acts were set up when the Us following the Great depression in the economy was reeling to recover by a process of isolation and not being able to be involved in the lobar state of affairs.

They had to revise the laws because they were able to see that a war with Germany was imminent and perhaps even unavoidable.

In this possibility the country had to make sure that it was in a advantaged position to trade with the Europeans and the law was thus passed and brought into place.
