On March 26, local time, US President Joe Biden delivered a speech on the conflict between Russia and Ukraine in Warsaw, Poland.

  Biden said that NATO is a defensive alliance, and Ukraine is not currently a member of NATO, so the United States does not need to directly intervene in the Russian-Ukrainian conflict. The US military in Europe is not for conflict with the Russian army, but to defend NATO allies.

  In addition, Biden repeatedly accused Russia in his speech, while saying that he needs to prepare for a long-term battle.
