who are “the summer soldier and the sunshine patriot”?

The "summer soldier" and the "sunshine patriot" are terms coined by Thomas Paine in his pamphlet "The American Crisis" published in 1776. They refer to individuals who support their country or a cause only during favorable or easy times but abandon it when faced with hardship or danger. The "summer soldier" is enthusiastic only when conditions are good, while the "sunshine patriot" supports the country only during peaceful or prosperous times but disappears when times get tough. Paine used these terms to criticize those lacking true commitment and to inspire perseverance and steadfastness amid the challenges of the American Revolution.
