A return of Cuba could draw Spain into the war

Could Spain join the war against the United States?

Potentially, if the Entente offered Cuba and Spain sought to reverse losses from the Spanish-American War.

Cuba is suggested as a possible inducement for Spanish entry against the United States. Recovering a major loss from the Spanish-American War supplies the proposed motive. Spain’s participation remains explicitly conditional rather than a predicted diplomatic outcome. No wider Spanish military plan or alliance negotiation is specified.
