Joe Biden’s last-gasp missile decision is momentous for Ukraine – but Putin will retaliate

US president Joe Biden’s last-gasp decision to permit Ukraine to fire western-made, long-range missiles at military targets deep inside Russian territory runs the risk of triggering a sharp increase in retaliatory sabotage, such as cyber and arson attacks on Britain and its European Nato partners.

Vladimir Putin, who ordered the full-scale, illegal invasion of Ukraine 1,000 days ago tomorrow, has long warned that Kyiv’s expanded use of US-, British- and French-made missiles would be viewed by Moscow as an act of war by Nato, and could trigger catastrophic consequences. Now Putin’s bluff, if it is a bluff, is being called.
