From the words used, Gen Hooda appears to be concerned about the situation which would mean he sees a real cause for worry and it’s isnt as simple as some are making it out to be.
On a related note, I would hope that we stop asking for the LAC to be demarcated etc except at closed doors official talks where such discussions may be pertinent. Otherwise, it looks like us whining. If the Chinese don’t want it, no reason to let on that we want it any more than they do. Senior military officers, retired or otherwise also should not be saying “diplomacy is the only thing that will work...” even if that was true. Leave that to the diplomats, unless military diplomacy is what is being spoken of. Worrying about Chinese belligerence is pointless, they will only stop when that no longer works for them. Some Indian belligerence may well be necessary.
