The more I think about this the weirder it gets. What exactly is the point? Let’s say they dig the poor chap up, go all CSI on his ass and find a bullet in his skull with a great big Union Jack or a hammer and sickle engraved on it. Then what? Is Poland going to break off diplomatic relations with the UK and/or Russia? I think not. Is Poland going to demand a public apology from the UK and/or Russia? There would be no point. No country is going to admit to that kind of skullduggery in living memory. At best it will just sour Poland’s international relations. So why do it?
Let’s plunge ever deeper into fantasy land and imagine the UK or Russia do admit to having killed Sikorski. Then what? Am I supposed to be astonished that assassinations and betrayals happened during the war? I would be astonished if they hadn’t. Surely that’s precisely the kind of thing we expect to happen in wars, that’s why we try and avoid them if possible. Am I supposed to believe that Poland or any other nation behaved with total honesty and honor? Of course they didn’t. Would Poland have secretly bumped off Churchill if it would have made their survival more likely? They would have been idiots not to try.
In reality they won’t find anything conclusive. Even if they do it won’t make the slightest difference. Conspiracy theories feed on details. The more details there are the more potential conspiracies you can squeeze out of them. JFK: one dead president, shot on camera, body in an autopsy suite within hours, result: conspiracy city. 9/11: thousands killed on live tv, years of meticulous forensics, 27 million hours of media coverage, result: conspiracy orgasm. Sikorski was buried in England for 50 years. Then he was exhumed and moved to Poland in 1993. I can think of 250 opportunities for conspiratorial shenanigans in those two facts alone, adding more ‘facts’ isn’t going to help.
This looks suspiciously like digging an official hole that is inevitably going to fill up with junk.
