Why is it important that the
federal government and the state governments have
separate as well as shared powers?

It's called "checks & balance"

Explanation:

this was enacted so the power to govern is shared, not just 2 1 group. that way any group opposed to a law has a "say-so" in the outcome of any law or rule..like Congress has to vote on a law the president approves.

to protect the united states' role as a world leader, president truman wanted to prevent the soviet union from spreading communism beyond its post-world war ii boundaries. he declared that the united states must assist any nations struggling to prevent a communist takeover.
