Despite the differences between Russian and Ukrainian, the two languages share many features. They are similar in vocabulary, verb conjugations, sounds, and grammar. They also have distinct noun and verb endings.

In the early days of the invasion, Russia was sending too few ground troops to the front line. Military analysts say this was a strategic blunder. They say Moscow would have had a much harder time resisting the numerically superior Ukrainian army.

A recent Gallup poll found that 70 percent of Ukrainians were determined to fight to the finish line against Russia. Ukraine has displayed resilience in adversity and has won plaudits from Western allies for its resistance.

In a broader sense, Russian and Ukrainian have a long history. They have coexisted for centuries. They have even evolved into a hybrid language, called Surzhyk, which is used in several parts of Ukraine.

The Soviet Union’s competition for power in the wake of World War II was both ideological and cultural. Putin has touted the country’s storied history and its contribution to greatness. But he’s also taken action to reclaim lost territories.

In the past, the US and NATO have supported the Ukrainian cause. The alliance has not slackened, even though prices for energy have skyrocketed. Nonetheless, a US President, Joe Biden, said Washington would not send military forces to Ukraine.

The United States and NATO are helping the Ukrainians maintain their right to self-defence. However, it’s not clear how long this will last. And Russia has not shown signs of being ready to negotiate a serious end to the conflict.
