The act that keeps people, countries, or races from work, opportunity, access, or recognition is known as Blacklisting.
- Blacklisting is the preparation of a blacklist wherein some people, countries, or races are blacklisted such that opportunities for work, access, or recognition will not be granted by those who prepared the list and similar entities.
There are numerous backlashes from blacklisting, including:
- loss of credibility and goodwill
- avoidance by the rest of the public
- decline in business contacts
- increased financial hardship
- Inability to function as a member of the group because of exclusion.
- The opposite of blacklisting is whitelisting. The latter involves inclusion and acceptance.
Thus, blacklisting makes a person or entity an outcast of a group, to be excluded, and prohibits interaction with the person or entity.

A. Germany was invading other European countries, the Allies declared war on Germany, Roosevelt signed the Lend-Lease Act but still refused to enter the war, Pearl Harbor was attacked, the United States entered the war.
The United States wanted to remain neutral and have no involvement in the war, however, the US did send resources to the Allied Powers. In 1939, Congress passed the "Cash-and-Carry" Provision; later in 1941, the Lend-Lease Act was passed. So far the United States did not have any direct involvement with the war, the US only supplied its allies. This all changed when the Japanese bombed Pearl Harbor; the US had to abandon their policy of neutrality and take action.
