Defence secretary Ben Wallace will soon be travelling to Moscow to meet Russia's defence minister, but he is lowering expectations of a diplomatic breakthrough. He says there is a chance a Russian invasion could be stopped, but he’s ‘not optimistic’. The UK's response to Russia's military buildup has been more muscular than most. They have supplied Ukraine with 2,000 light anti-tank weapons and troops to help train them. But not all NATO allies are willing to do the same. Germany's new government warned ‘supplying Ukraine with weapons could escalate the conflict’. Instead, Berlin is supplying Ukraine with ‘non-lethal’ field hospitals and 5,000 military helmets. Poland and Latvia have publicly criticised Germany's stance. Wallace hopes that Germany will support tough economic sanctions. After meeting NATO’s secretary general, Mr Wallace said the UK could support NATO by ‘increasing forces on land, sea or air to deter any further Russian aggression’, and could send Ukraine more weapons.
