Amidst the Ukraine war, the US Senate has given the green signal to Sweden and Finland to join the North Atlantic Treaty Organization (NATO). NATO organization NATO is nearing its most significant expansion in decades following the decision of the US Senate. Both the US Senate and the Italian Parliament on Wednesday approved Finland and Sweden joining the 30-member NATO organization. The US Senate has taken this step at a time when Russia is completely embroiled in the Ukraine war. The special thing is that the main reason for the war between Russia and Ukraine was its interest towards NATO. Russia attacked Ukraine only because of its membership of NATO. Russia may once again be aggressive regarding the NATO membership of Sweden and Finland.
