“when andrew johnson took upon himself the duties of his high office he swore to obey the constitution and take care that the laws be faithfully executed. that, indeed, is and has always been the chief duty of the president of the united states. the duties of legislation and adjudicating [making a judgment on] the laws of his country fall in no way to his lot. to obey the commands of sovereign power of the nation, and to see that others should obey them, was his whole duty—a duty which he could not escape, and any attempt to do so would be in direct violation of his official oath…”

according to the quotation, why does stevens believe that johnson should be removed from office?

the correct answer is modern american cars are not available due to trade restrictions.

trade between cuba and the united states have serious restrictions. the u.s. imposed an economic embargo on cuba, that among other things means that modern american cars are not available due to trade restrictions.

in response to some governmental actions of the authorities from cuba, president john f. kennedy proclaimed an embargo on trade between both countries in february 1962. the trade embargo remains active until this day and was implemented directly by the departments of commerce and the department of treasury.

in president trump’s administration, there is a national security presidential memorandum that "strengthens the policy of the u. s.", affecting trade with cuba.
