The French, perhaps - they had a large army and a lot of capability. The British did not. Hitler would not have paid any attention to a threat from the British, because they didn't have the ability to enforce a threat.

Chamberlain didn't buy time, he put Britain in a weaker position by allowing Germany to grow confident and divide up a powerful Czech nation.

The United States sent Britton emergency shipments of previously un-issued Civil War era Spencer rifles. The Spencer was the first military repeating rifle with a .50 cal, short range magazine in the stock which I believe held 10 rounds.
