It is unclear which country's independence is meant
for independence
Not directly. The Independence of Israel was the direct cause of the Arab-Israeli War of 1948 (the Israeli Independence War), not the Arab-Israeli War of 1973 (the Yom Kippur War). The cause of the Arab-Israeli War of 1973 was for Egypt to reclaim the Sinai Peninsula and for the Syrians to reclaim the Golan Heights, both under legal Israeli Occupation pursuant to UNSC Resolution 242. However, if Israel had not achieved independence, it could not have occupied those territories and there would have been no Yom Kippur War, but this is probably not what the question was looking for.
Yes, the root cause of the war was the quest for Cuban Independence.
It began with the Grito de Dolores as a demand for Independence from Spanish rule.
One long term cause of the Spanish American War was to protect American business interests in Cuba. Another cause was America's support for Cuba's independence.

The underlying cause of the Spanish American War was US public support for Cuban independence. The triggering event was the mysterious sinking of the USS Maine on 15 February 1898 which led to a declaration of War. The net effect of the War was Cuban Independence and the loss of Spain's New World Empire.
Fight the war.
The causes of the Declaration of Independence was the increase in british troops in the thirteen colonies in America and a war, the American Revolution, that lasted about 5 years.
