What is the thinking behind using "let" here?
Lets you and him make peace.

>>What's the subject of "let"? Is it "I"?

It is historically "us", and is cognate with and equivalent to Dutch "laat ons", Low Saxon "laat us" or "laat uns", and Swedish "lat oss" (for examples in other Germanic languages).
How can "us" be a subject when it's an object pronoun?
I got confused for a second there, sorry. Oh, those are morphologically imperative, with an implicit second person subject.

These to me are ungrammatical without a preceding subject, and then the "-s" would have to be the third person singular present marking. However, there may very well be dialects in which reanalysis has taken place such that "let's" has lots its verb-like vestiges.
That should be "lost its".
