Speaking about drones, it's an excellent area in which the western countries can help Ukraine get better situational awareness of what's happening. The OSCE has flown drones as part of its mission in Ukraine but has found that they've been hijacked or been shot at and that sort of thing. The OSCE, then, also needs support to back its ceasefire monitoring in Ukraine.
