Why would cuba feel the need to strengthen its defenses after the bay of pigs?

After the Bay of Pigs, Cuba would understandably try to strengthen its defenses. The reasons for this are that the country was directly attacked on its own soil.

Most of the people that left the country because of the government were obviously ready to fight against Cuba if sponsored and backed by someone.
