What problems in dealing with foreign nations sud’s the articles of confederation present?

The Articles of the Confederation created a decentralized political union in which the powers of the Continental Congress were severely limited, and the rights of the states, on the contrary, were expanded. In the era of the War of Independence, the United States began to create foreign affairs agencies, but real powers were concentrated in the hands of individual politicians and American envoys to Europe. The period of the American Revolution and the post-war period were also characterized by the development of the concept of neutrality and the principles of public diplomacy, which have become part of the United States foreign policy doctrine for more than a century.

According to the Articles, the Confederation resolved issues of war and peace, diplomacy, Western territories, money circulation and state loans, while the remaining issues were given to the consideration of the states. It soon became apparent that the powers of the Confederate government were very limited and this weakened the unity of the new state.

It was still a weak and ineffective government - that was what the Articles meant. Congress did not have the ability to control trade. It concluded treaties with foreign powers, but could not force the states to execute them.

Explanation:

on 6 november american voters will elect members of the house of representatives and the senate, which together are called congress.

both houses of congress are currently controlled by the republican party, which backs president donald trump.

the democrats think they can win control of the house of representatives this year by winning a majority of seats.

doing so would let them block or delay the president’s plans by refusing to enact them.

all 435 seats in the house of representatives are up for election.

if the democrats want to take control of the house by having the most seats, they’re going to have to claim at least 23 from the republicans.

so, based on the research i've done. the u.s. government were always on a wild goose chase just to take down castro. he then retired his trone to his brother raul in 2008 due to some health issues. so it's obvious your answer would be:

castro had no allies from which he could receive aid.

hope this and have a fantastic day!
