>George Washington didn't want any standing fighting force after the Revolution and we can debate as to why, personally I think he saw a standing military as a threat that potentially could overthrow him.

This isn't remotely true. Washington's anger at militia forces is well documented. He hated their lack of discipline, saw them as little better than a mob, and was disgusted with their cowardice.

It's not hard to find sources for this.

George Washington was not a big writer, and still managed to turn out this long letter, probably one of his longest, just about problems with militia forces. https://founders.archives.gov/documents/Washington/03-06-02-0305
