The ukrainians can defend, but honestly, theyre not an offensive power. So no need to worry.Send Ukraine 1,000 Pattons and 4,000 M113's, youre kidding? The rationale is more likely that noone wants to see Ukraine become a regional power. Its already probably the strongest army in Europe apart from Russia. I mean who could beat Ukraine in a fight now? British? French? I dont think so. Maybe British with the F35's but they still lack land forces to beat Ukraine.
The trick is to defeat russia without creating a ukranian monster.
