As the Iberian Peninsula is surrounded almost entirely by water, the most likely way of invasion would be by sea/boat.
because it's right
An invading army would most likely invade Spain via sea routes due to its geographic isolation and the surrounding oceans. Historical examples include invasions by the Carthaginians, Romans, Moors, and Napoleon, all of whom utilized maritime routes to launch their attacks. The Strait of Gibraltar offers a narrow passage that facilitates access between Spain and North Africa, enhancing the feasibility of sea invasions.
