I am on a spectrum.
In the ashes of the collapsing Russian Empire in the early 20th century, the peoples of Eastern Europe found themselves at a crossroads. To their east, a devastating Civil War would eventually forge a Menshevik Socialist Republic eager to liberate the workers of the dead Tsar's former richest holdings. To their west, a hungry and unrestrained Kaiser was gazing toward Kaunas, Brest, and Lviv. The hastily organized constellation of ethnic republics that were declared in the wake of the march on St. Petersburg were thrust into immediate existential crisis that could only be averted through one thing - cooperation. When a combined column of Lithuanian partisans and Ukrainian volunteers miraculously stymied a German expeditionary force at the Battle of Krakoviec, the cooler heads of the German diplomatic corps met with the desperate Slavic Republics to form what was intended as a buffer with the "Labour flanking maneuver" establishing itself in Moscow. The resulting Treaty of Klaipéda created a permanent organization of the smaller states of Eastern Europe, one poetically described as the Commonwealth of Nations or the New Intermarium, but officially designated in English as the Kievan-Lithuanian Pact.
The intervening centuries have been no less chaotic and fraught than any in the history of Europe's borderlands, sandwiched as they were between two of the world's major empires and the weakened but no less intimidating Menshevik Russia, but the KLP has persisted through deft diplomacy, economic indispensability, and sheer paranoia. The initial treaty, with its guarantees of cultural sovereignty and obligations of military cooperation, formed the basis for relative internal peace and, at the behest of the economically dominant governments in Kaunas and Kiev, an eventual "Slavo-Baltic Federalism" tying the Pact close enough together to form a true state. As an economic union, the various republics formed a natural trade conduit between three neighbors hungry for both raw resources and outsourced industry, and eager for excuses not to fight industrialized war with each other despite their wildly varying ideologies. And as nations in one of Earth's least defensible geographic positions, the combined Pact military-espionage complex became exceedingly skilled at learning of, and reacting to, potential threats.
The lattermost factor proved decisive in the next great war that brought an end to the peace of the early Golden Millennium, the Five Year War. The KLP's steady buildup of conventional arms for its territorial defense formations, and the latest-generation mobile suits reserved for its professional army, successfully turned back attempted incursions of its territory, while their light, neo-colonial hand on their space colonies prevented any major reversals or spacenoid nationalism from crippling them economically. With their massed armored formations and one extremely lucky mobile suit pilot once again handing them a seemingly-miraculous victory at the Battle of Odessa, the Five Year War's groundside fighting was kept further east, much to the detriment of the Menshevik Republic. The socialist government's eventual complete collapse presented a never-before-seen opportunity to a federal government flush with victory from the war, and it was with no small amount of relish that Kyivan-Lithuanian (now the preferred transliteration after a diplomatic memorandum in GM0084) military moved quickly to secure the former Russian territory as peacekeepers and restorers of order, doubling the union's population and more than doubling its territory. That said, while the united governments insist that their occupation is a restoration of order, this remains de facto the first territorial acquisition by military force in the Pact's history, and the mass absorption of socialist former-enemies with shared roots but hundreds of years of diverged culture is likely the greatest challenge yet faced by the Pact.
