These two matters are essentially one, dependent on the attitude of the British. Until the day Spain no longer fears the British, perhaps reclaiming Gibraltar and annexing Portugal can occur simultaneously.
The complete Iberian Peninsula is an extremely perfect land, surrounded by the sea, with only the northeastern border touching France.
By deploying troops and building fortresses on both sides of the Pyrenees Mountains, enemies can be kept outside of the Iberian Peninsula.
If you add the vast plains of Portugal, Spain will gain large tracts of arable land, enhancing Spain's agricultural strength.
A complete Iberian Peninsula can easily accommodate over 70 million people. Plus, with Carlo's plan to localize the Moroccan region, these lands can accommodate nearly 100 million people.
Though not as expansive as countries like the United States with vast land and plains, this population capacity is relatively strong compared to other European nations.
