Sabre-rattling

“Sabre-rattling” (also spelled “saber-rattling”) is when a person or a government threatens to use force against another, just as a soldier rattles a sabre against an enemy. “Sabre-rattling” was commonly associated with Germany in the 1910s, both before and during World War I.
 
The term “sabre-rattling” has been cited in print since at least 1886. “Saber rattling” was used in a newspaper headline in 1908 and “sabre-rattling” in a newspaper headline in 1909. The Kölnische Zeitung (Cologne Gazette) used the term by at least the 1900s and possibly popularized “sabre-rattling” at an earlier date.

Wikipedia: Saber noise
Saber-noise or saber-rattling (Spanish: ruido de sables) may be used to refer to a historical incident in Chilean history that took place on September 3, 1924, when a group of young military officers protested against the political class and the postponement of social measures by rattling their sabers within their scabbards. This is not the origin of the phrase, however; in speaking at an American Congressional hearing of the need for Pacific coast fortifications to address the rising militarism of Japan, on February 21, 1921, Congressman John F. Miller made repeated reference to Japan as the place “where the saber is rattling”, and it is apparent that it was regarded as a common figure of speech at the time.
 
The term is now applied generally to cover any indication of military aggressiveness. In a sense, strategically timed war games can serve as an explicit form of saber-rattling, in that the extent of a country’s military muscle is put up on display for other countries (namely, adversaries) to see.

The “Gazette’s” is the most severe comment that appears among the weighty German journals, which generally continue their moderate tones. The Jingo press, on the other hand, is doing a great deal of sabre-rattling, their indignation being mainly directed against Great Britain, notwithstanding the fact that Admiral Kautz, the American commander, took the lead in precipitating the bombardment.
