Do you think states should always obey federal laws and why?

No

Explanation:

The word "always" implied that the states should obey the federal government under any circumstances.

Most of the times, yes. I think it is important for the states to obey the federal government in order to maintain law and order in the country.

But, there's a chance that the federal government might impose a legislations that's violates the constitutions or human rights. At that point, the states need to be able to raise as the opposition from the central government.

but whats the question? ?

explanation:

they wanted the u.s. to fight on the side of the central powers.
