In practice, because of sovereignty, any state can withdraw from any treaty at any time. The question of whether this is permitted is really a question of how other states will react to the withdrawal; for instance, another state might impose sanctions or go to war over a treaty violation.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Although withdrawal from a treaty may not be possible in theory, when might it be possible anyway?
Ah, so.. In practice

Much of El Salvador was home to the Pipil, the Lenca, Xinca, and Kakawira. The Pipil lived in western El Salvador, spoke Nawat, and had many settlements there, most noticeably Cuzcatlan. The Pipil had no precious mineral resources, but they did have rich and fertile land that was good for farming. The Spaniards were disappointed not to find gold or jewels in El Salvador as they had in other lands like Guatemala or Mexico, but upon learning of the fertile land in El Salvador, they attempted to conquer it. Noted Meso-American indigenous warriors to rise militarily against the Spanish included Princes Atonal and Atlacatl of the Pipil people in central El Salvador and Princess Antu Silan Ulap of the Lenca people in eastern El Salvador, who saw the Spanish not as gods but as barbaric invaders. After fierce battles, the Pipil successfully fought off the Spanish army led by Pedro de Alvarado along with their Mexican Indian allies (the Tlaxcalas), sending them back to Guatemala. After many other attacks with an army reinforced with Guatemalan Indian allies, the Spanish were able to conquer Cuzcatlan. After further attacks, the Spanish also conquered the Lenca people. Eventually, the Spaniards intermarried with Pipil and Lenca women, resulting in the Mestizo population which would become the majority of the Salvadoran people. Today many Pipil and other indigenous populations live in the many small towns of El Salvador like Izalco, Panchimalco, Sacacoyo, and Nahuizalco.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): El Salvador was home to which indigenous peoples?
Ah, so.. the Pipil, the Lenca, Xinca, and Kakawira

The Armenian Genocide caused widespread emigration that led to the settlement of Armenians in various countries in the world. Armenians kept to their traditions and certain diasporans rose to fame with their music. In the post-Genocide Armenian community of the United States, the so-called "kef" style Armenian dance music, using Armenian and Middle Eastern folk instruments (often electrified/amplified) and some western instruments, was popular. This style preserved the folk songs and dances of Western Armenia, and many artists also played the contemporary popular songs of Turkey and other Middle Eastern countries from which the Armenians emigrated.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where did the Armenians emigrate from?
Ah, so..
Turkey and other Middle Eastern countries
