remember the Maine(, to hell with Spain)

A US rallying cry in support of the Spanish–American War. Refers to the Maine, a US battleship destroyed in Havana in 1898. When this happened, the US and Spain were already at odds over Spain's treatment of Cuba, so the explosion was seen as an escalation in tensions, though Spain's role in it was never proven. Though many Americans were not exactly eager to go to war with Spain, the incident with the Maine changed public opinion on that front. "Remember the Maine" soon became a popular refrain.
