Keeping the Peace by giving it into an aggressors demands is known as what?

Appeasement

Explanation:

"Appeasement" is the process of giving the aggressor what it demands in order to retain peace and order. A perfect example of this is the "Munich Agreement" on September 30, 1938. The Great Britain avoided getting into war with Germany by engaging in this diplomatic strategy that it will not interfere with the plan of Hitler to annex Sudetenland. So, in this case, it gave Germans what they demanded. This is the reason why the conquests made by Hitler were not made known to the public in Britain.

Easy cases are almost always resolved correctly by lower courts. If there doesn't appear to be a possibility of the lower court having made an error, the Supreme Court will decline to hear the case. Also, the Supreme Court has far too little time to hear every case sent to it, so it will tend to turn down cases that don't deal with important and difficult Constitutional issues.
