By spring 1950, Stalin believed the strategic situation had changed. The Soviets had detonated their first nuclear bomb in September 1949; American soldiers had fully withdrawn from Korea; the Americans had not intervened to stop the communist victory in China, and Stalin calculated that the Americans would be even less willing to fight in Korea—which had seemingly much less strategic significance. The Soviets had also cracked the codes used by the US to communicate with the US embassy in Moscow, and reading these dispatches convinced Stalin that Korea did not have the importance to the US that would warrant a nuclear confrontation. Stalin began a more aggressive strategy in Asia based on these developments, including promising economic and military aid to China through the Sino–Soviet Friendship, Alliance, and Mutual Assistance Treaty.
What country did not prevent a Communist victory in China?
US

Detroit has a Mexican-American population. In the early 20th century thousands of Mexicans came to Detroit to work in agricultural, automotive, and steel jobs. During the Mexican Repatriation of the 1930s many Mexicans in Detroit were willingly repatriated or forced to repatriate. By the 1940s the Mexican community began to settle what is now Mexicantown. The population significantly increased in the 1990s due to immigration from Jalisco. In 2010 Detroit had 48,679 Hispanics, including 36,452 Mexicans. The number of Hispanics was a 70% increase from the number in 1990.

As in the other Western Romance languages, the main plural expression is the suffix -s, which may create morphological alternations similar to the ones found in gender inflection, albeit more rarely. The most important one is the addition of -o- before certain consonant groups, a phonetic phenomenon that does not affect feminine forms: el pols/els polsos ("the pulse"/"the pulses") vs. la pols/les pols ("the dust"/"the dusts").
What can the addition of the suffix -s produce?
morphological alternations
