Which will likely be immediately called out as so. See recently (few days ago) when Orban's goons put explosives on gas pipes in Serbia going towards Hungary and then loudly blaming Ukraine.

Everybody immediately knew that this would make no sense for Ukraine to do that - i.e. Why would they just plant explosives to be found, when they would blow it up on spot if they really wanted?. Whole thing kind of fizzled out because nobody took the bait.
