The X community added a note to the post that read: "Readers added context they thought people might want to know. The reason for NATOs existence is explained in its preamble: "to safeguard the freedom, common heritage and civilisation of their peoples, founded on the principles of democracy, individual liberty and the rule of law." nato.int/cps/en/natoliv… The Warsaw Pact was established 6 years after NATO. nato.int/cps/en/natohq/…" The label is part of X’s Community Notes system.
