Of course, very serious implications happened globally. Britain and Spain were almost bankrupt from recent wars, and France, despite recent good fortune, was also nearly bankrupt. The Dutch were very wealthy, and Portugal was not too changed. Finally, the Holy Roman Empire was about to undergo serious change. Other major nations around: Russia, the Quin Dynasty (China), Japan, Ethiopia and the Ottoman Empire
First of all, Spain had the most serious change. Losing Louisiana was okay, but Mexico and Cuba made them made, not to say the Dutch taking Venezuela. Finances were ruined. The kingdom finally fell into rebellion 2 years after losing the First War for the Americas, with the Army, Navy, and people going rouge. They quickly took out Madrid and installed a republican government, with a Parliament based of the U.S. Congress, with states including Castile and Leon, Aragon, Galatia, and others. A elected King, President of Parliament was chosen, and the quick Spanish revolution turned Spain to the side of France, the Netherlands, and the fledgling U.S.
Britain took a hard hit. It had lost its crown jewel, and despite retaining British Honduras and Bermuda, they knew it was time to expand. They invested in South Africa and India in earnest, and explorer James Cook discovered a new land, and name it New Britain, with Georgetown on the islands west coast its capitol (This is OTL Australia). The recession caused by the lose of the war and the colonies was recovered from by 1790, just in time for more conflict...
France had made strides in the war, taking half of former Spanish Mexico, the East half of Cuba, and a victory over Britain. However, its treasury ran dry. King Louis XVI decided to sell off the west half of Cuba to the U.S, approved by Congress, and Washington, Mason, and Adams in 1786, for the price of $7 Million dollars. They barely avoided revolution.
The Netherlands were particularly happy, having gained victory over Britain and expanded a South American colony. New Amsterdam was decided as the colonial capital (not yet built) and a future new colony in Africa seemed possible.
The Holy Roman Empire was founded around 800 A.D., built was on the verge of collapse. Its allies persuaded various kings to have a constitutional convention in Berlin in 1785, but that is for next time.
