1. We enforce a tight blockade with our Toledo-Class warships, stopping Algerian and Tunisian trade in the Mediterranean. With France being forced to give up all colonial claims, they can only watch. 2. We launch an offensive from our Moroccan territory, utilizing tanks and motorized infantry to cover huge swathes of worthless desert, a strategy common in WWII. 3. We perform large-scale aerial and coastal bombardments in Algeria, disrupting defenses and allowing us to get the jump on them. 4. We also bomb Tunisia, damaging military infrastructure such as runways and naval ports, allowing marines to storm in uncontested. 4 (Yellow, I accidentally made two). We launch massive attacks from all sides on Algeria, utilizing 400,000 war-hardened veterans to quickly storm their beaches and completely overwhelm them before they can put up any kind of defense. 5. We launch large marine operations on Tunisia, quickly swarming their populated areas and forcing them to surrender or face destruction. 6. We support supply lines via a chain of multiple islands, creating a strained but steady supply of food for our soldiers. 7. Okay, I never got to use this plan until now, but now our military is vastly more powerful. All previous invasion plans stand, but the troops double in number and experience. Our jets are also more modern, as we are now using the T-72.
Due to technological advantage and massive industrial gap, Spanish war games have predicted that this will not even be a war-just a quick military operation. The inexperienced Algerians and Tunisians have little heavy weaponry, presenting a very high possibility of this operation becoming a slaughter if the enemy attempts to resist. [EDIT] - I made this back in 1969, I just had everything planned but I never got to use it until now. However, we are even more powerful now, and have a larger navy.
