Polish invasion of France (September 2012)
The Polish invasion of France is called when France was invaded by Poland with the help of Republic of Macedonia (FYROM) and Spain, after an agreement between French and Polish governments, because of Poland took over France before, and France was looking to reach peace with Poland and have congress.
Poland invaded entire France time ago, with the exception of Aquitaine, in hands of USA, so France wasn't able to have congress. France tried many times to free one region, but all resistance wars were useless. They reached an agreement with Poland, so polish let them free some regions, keeping the useful for them because of resources.
The agreement didn't include the region of Rhone Alps, and Poland asked France to declared them Natural Enemy to have back that region. France denied the request of Poland, and the war started. Poland talked to Spain and Republic of Macedonia (FYROM) to help them.
Spain at the time of the war was controlling all of Portugal and some regions of Venezuela after an agreement with them. Taking the opportunity, Spain was declared as Natural Enemy by Portugal and Colombia. Spain, after losing the resistance war of Midi-Pyrenees, left the war and focused on their own fronts.
France was left with only one region, Corsica. USA, country that used to have Aquitaine region, didn't want to Republic of Macedonia (FYROM) had it. At first was conquered by Poland, but then was liberated and conquered by Republic of Macedonia. This gave a border between USA and Republic of Macedonia (FYROM), that led to the Republic of Macedonia (FYROM)–USA War.
