What is "peace for our time"

n. 1 (non-gloss definition: Used to evoke the situation where an aggressor is being appeased for the sake of delaying a (possibly inevitable) war) 2 (non-gloss definition: Used to evoke the idea of false political promises and false expectations.)

"Peace for our time" is a phrase spoken on 30 September 1938 by British Prime Minister Neville Chamberlain in his speech concerning the Munich Agreement and the Anglo-German Declaration. The phrase echoed Benjamin Disraeli, who, upon returning from the Congress of Berlin in 1878, stated, "I have returned from Germany with peace for our time". It is primarily remembered for its ironic value: less than a year after the agreement, Hitler's continued aggression and his invasion of Poland was followed by declarations of war on Germany by France and the United Kingdom.

It is often misquoted as "peace in our time", which had appeared long before in The Book of Common Prayer as "Give peace in our time, O Lord", probably based on the 7th-century hymn " Da pacem Domine! in diebus nostris, Alleluja". It is unknown how deliberate Chamberlain's use of such a similar term was; however, anyone of his background would have been familiar with the original.
