To my knowledge the US never declared war on Texas. However, after Texas became a US state it did lead to a declaration of war on Mexico. And Texas was at war with the US during the Civil War, but that was because Texas seceded from the Union and joined the Confederacy.
Germany declared war on the US, the US then declared war on Germany.
The US declared war on Japan. Germany also declared war on the US, and the US declared war in return
I don't think that the US declared war on Germany. Germany declared war on the US on December 11th 1941
The Italians declared war on the US on December 11, 1941, along with their German allies.
The last US declared war was WWII.
The US declared war on Germany on December 11, 1941 in response to Germany's declaration of war on the US earlier that day. In a separate act on the same day, the US declared war on Italy, which had also declared war on the US. Germany and Italy declared war on the US in response to the US declaration of war on their ally Japan on December 8, 1941 in response to the Pearl Harbor attack.
The US Civil War was an un-declared war.
Five months after Texas was granted statehood, a Mexican attack on US troops (and a US fort) allowed Polk to go to war with Mexico. Congress declared war on May 13, 1846.
The US did enter into an undeclared shooting war with Germany in the fall of 1941 because Germany has declared war on the US.
Yes. If the question is regarding a "declared war" or not; there hasn't been a US declared war since WWII. The US Civil War (1861-1865) was not a declared war either.
England - just after US declared an independence.
