Any ideas why?
Sure...Attack primarily directed against Russia/Putin...Like Metro attack...West is again in a 'cold war' with Russia over pipelines, resources and Russian policy with Iran...All intelligence services/mafiya operate in Caucasus, which is pipeline route, and next to Caspian oul/gas fields, and Iran...Where you think Chechen rebels get money from?...Jewish oligarchs in London, Israel, elsewhere, CIA slush fund money too.
West/Zionists/NWO do not wish to see better relations between Poland and Russia...No 'Slavic unity' odf any kind in NWO allowed...So, kill two birds, one stone...Humiliate Russians at site of Katyn, wipe out 'right wing' Polish leadership, smooth way for Sikorski, favorite of Rothschilds, to move in...Actually, West give a sh*t about Kaczynski, but he serve a purpose dead.
Also, London/Brussels bankers did not like devaluation of złoty...This action showed too much independence for NWO/EU crowd...Poland must be kept 'off to the side' unless it wishes to join global plantation system fully...What a couple dead Poles to them?...Remember the 'loyalty' of Allies at Yalta and elsewhere?
On related threads I post RIA Novosti 'dramatization' of crash...Video animation clearly shows plane EXPLODING right before touchdown...Wing hitting treetop, especially the relatively light trees near airport, DO NOT CAUSE EXPLOSION.
Of course, this only 'dramatization'...But guess what?...Findings from 'black box' recovery will very likely never be made public, as contents will be too inflammatory...Announcing bomb or explosion will mean head on collision with 'certain elements'...Do Russia or Poland want this?
Just MHO, but I try to answer your question.
