Who declares war and maintain military?

Question

State power or federal power?

Answer 1

In most countries, the power to declare war and maintain a military is typically vested in the hands of the federal government or the central authority. This is because matters of war and defense usually fall under the purview of a nation as a whole rather than individual states or regions within that nation.

However, it's important to note that the distribution of these powers can vary depending on the country's political system. Some countries with a federal system may grant certain military responsibilities to individual states or provinces, especially in matters of internal security. These states or provinces may have their own police forces or militias to address local security concerns, but the ultimate authority for declaring war and maintaining a national military generally resides with the federal government.
