US Army General George Washington who was also the first President of United States of America was believed to have came out with the quote "a nation is judged by how well it treats its veterans". As he was an Army General himself and had led the then US Continental Army in the United States fight for independence, it is not a surprise that the quote was attributed to him.
The quote, while may have not be from him, unfortunately is very correct. If a country is not able to honour the men and women that had signed up to serve their nation at the nation's time of need, by treating these men and women well, then what honour does the nation has?
While the original quote was from a US President on the treatment of US veterans, this quote is very much a reflection of our own country.
