NATO leaders are set to approve plans outlining how the alliance can respond to an attack by Russia, marking the first time since the end of the Cold War that such detailed plans have been drawn up. The move comes as a top NATO official warns that preparations are needed because "a conflict can present itself at any time." The plans, running into thousands of pages, will also guide its 31 members on how to upgrade forces and logistics.
