Thx.
There is nothing wrong with soliciting ideas. Zero.
I was taught that there is nothing wrong with doing it when making plans. Go ahead and ask for ideas. The cardinal rule is to turn it around, treat it as your own idea. Modify it and make it yours. Most of all, in the end, it is your responsibility. If it works, recognise the effort created by someone else and carry on. If it fails, you take 100% of the blame for it and only you.
Again, I'm extremely leery of statements made by unidentified sources, especially when reported by media like CNN.
We should carry out wars according to LOAC. Not Miss Manner's on Combat.
