And Poland is not a threat to Russia.
Agreed. But up to a moment of placing US/NATO military bases with strategic weapons in Poland. Since then - targets in poland is loaded to ICBM warheads, because there is no other choice.
And, concerning malaysian Boeing...
1. No any local evidences that BUK missiles ever started from the area. The trace from missile goes to clouds and keeps visible in the air for up to 10-15 minutes. Roar is so loud so can stuff up the ears for few km. from a launch pad. It is not some thing that can pass unnoticed by a nearby people.
2. Usually, minimum of 2 BUK missiles fired to a important target, as hit probability is 0.6-0.85.
3. A few experts (former Air Defence officers) already noted that few visible points of damage on Boeing fuselage parts on published photos looks like it was made by striking elements (tungsten pins) of R-60 (NATO - AA-8 Aphid) air to air missile, not by much more powerful Buk.
4. Unites States definitely have their own satellite photos and radar data for this area, but keeps it classified. Russia is published theirs already. It would be easy to point to any inconsistences (if there is any) in the data published by Russia, but US officials still operating by a junk taken from Youtube and Twitter. So, either russian data is correct (and ukrainian fighter jet is really made some sort of "jump" to Boeing just before their crash) and US does not wish to confirm it, either there is some other facts that US does not wish to make public.

Unreleased data from a black box retrieved from the wreckage of Malaysia Airlines Flight 17 in Ukraine show findings consistent with the plane's fuselage being hit multiple times by shrapnel from a missile explosion.
"It did what it was designed to do," a European air safety official told CBS News, "bring down airplanes."
The official described the finding as "massive explosive decompression."
...
They are finding more evidence, though, of the sort of blast holes through the plane that an exploding missile might make. The Dutch say their full team will concentrate on this sort of specific find.
