NATO must be prepared to fight to defend its territory: British general

Britain and its Western allies must be "unequivocally prepared to fight" if Russia launches an attack on NATO territory, the new head of the British army said.
General Patrick Sanders, the chief of the general staff (CGS), said Russia is likely to emerge from the conflict in Ukraine as an even greater threat to European security.
In his first public engagement since taking up his post, he said it is essential NATO has the forces in place to deter future "land grabs" by Russian President Vladimir Putin.
Speaking at the Royal United Services Institute land warfare conference in London, he warned any further cuts to the size of the British Army would be "perverse".
His address came as NATO leaders gathering for a summit in Madrid were preparing to massively increase the numbers of troops on high readiness to more than 300,000.
Sanders likened the current situation to the run-up to World War II, saying Putin's "brutal aggression" in Ukraine represents the greatest threat to European peace and democracy in decades.
"This is our 1937 moment. We are not at war, but must act rapidly so that we aren't drawn into one through a failure to contain territorial expansion," he said.
"In Ukraine, we have seen the limitations of deterrence by punishment. It has reinforced the importance of deterrence by denial.
"We must stop Russia seizing territory rather than expecting to respond to a land grab with a delayed counter-offensive.
"To succeed, the British army, in conjunction with our NATO allies and partners, must be in place or at especially high readiness – ideally a mix of both. Trip wires are not enough.
"If we fail to deter, there are no good choices given the cost of a potential counterattack and the associated nuclear threat.
"We must therefore meet strength with strength from the outset and be unequivocally prepared to fight for NATO territory."
Sanders said the threat from Russia raises questions about the future size of the British army.
"Put simply, the threat has changed and as the threat changes we will change with it," he said.
"It would be perverse if the CGS were advocating reducing the size of the army as a land war rages in Europe and Putin's territorial ambitions extend into the rest of the decade and beyond Ukraine."
Despite Russian setbacks in the early weeks of the campaign in Ukraine, it still has the capacity to recover and pose a renewed threat to European security, he warned.
"Historically, Russia often starts wars badly. Because Russia wages war at the strategic and not the tactical level, its depth and resilience means it can suffer any number of campaigns, battles and engagements lost and yet regenerate and still ultimately prevail," he said.
"While Russia's conventional capability will be reduced for a time at least, Putin's declared intent to restore the lands of historic Russia makes any respite temporary and the threat will become even more acute.
"We don't know how the war in Ukraine will end, but in most scenarios, Russia will be an even greater threat to European security after Ukraine than it was before."
