If the United States were to impose an embargo against Saudi Arabia’s oil, targeting only ONE ITEM, this would be an example of what?

It would be an example of an economic sanction.

Explanation:

Economic sanctions are the measures taken by a nation to punish economically and financially another for its breaches, be they commercial or legal, committed against the sanctioning nation itself, or against others, or against citizens of these nations.

Thus, through the imposition of tariffs, embargoes, freezing of accounts, etc., nations seek to cause economic damage that is the reason for the cessation of the actions that motivate the sanction. For example, the imposition of tariffs by the US on China during the 2019/20 Trade War was intended to stop the dumping carried out by the Chinese government.

the united states constitution is the supreme law of the united states. the constitution, originally comprising seven articles, delineates the national frame of government. its first three articles embody the doctrine of the separation of powers, whereby the federal government is divided into three branches: the legislative, consisting of the bicameral congress; the executive, consisting of the president; and the judicial, consisting of the supreme court and other federal courts. articles four, five and six embody concepts of federalism, describing the rights and responsibilities of state governments, the states in relationship to the federal government, and the shared process of constitutional amendment. article seven establishes the procedure subsequently used by the thirteen states to ratify it. it is regarded as the oldest written and codified national constitution in force.
