In your initial post, you stated that the Bonus Army failed. I maintain that it succeeded beyond its expectations--as indicated in the article that you yourself linked.
Although it appeared at the outset to be a failure, the Bonus March and the governmenht's over-reaction to it stimulated public sympathy, as reflected in films such as Gold Diggers of 1933, helped to bring down the Hoover administration--and ultimately won the marchers their bonus.
Did you miss the part where the Federal government was more than willing to gas, shoot, and kill American citizens who were peaceably exercising their God Given and Constitutionally guaranteed First Amendment rights?
Did you catch the names of the Officers in charge of the Federal troops who did the killing?
If you think shutting down DC will bring a different reaction this time around you're hopelessly naive.
