I hate Kaczynskis, but what they are doing outside Poland is nothing compared to what they are doing inside of it.
Now for the details.
You say Poland attacks Russia. Au contraire. Russia was using lately oil and gas pipelines to exert pressure on nations such as Georgia, Ukraine and Belarus. It's closed pipeline to Belarus for some time, cutting Poland from oil as well. No earlier warning. Milions lost.
Poles, not Russians, bought a rafinery in Lithuania - "accidentally" just after it a fire destroyed it, and - what a coincidence - Russians closed the pipeline to it "for maintenance" - only to say quite frankly later on that since Poles bought it, they are not interested in fixing the pipeline. Please compare it to closing "for maintenance" pipelines and railways to Estonia as well.
Russia, to punish Poland for support towards independance of Ukraine, has decided to build a pipeline through Baltic Sea, to by-pass both. It was planned through polish economical zone of it - they forgot to ask for permission.
While Gorbaczew and Yeltzin admitted Katyn massacre was commited by Moscow, now Putin tries to back out of it. Russia promessed help in the investigation, but it has closed its own, and - despite promesses - denied documents concerning this matter.
Also after polish involvement in Ukraine, Russia introduced boycott of polish foodstuff, mostly meat. Also according to EU - without any basis for it.
AND IT WAS ONLY AFTER POLAND VETOED AN ECONOMICAL DEAL THAT WAS IMPORTANT FOR WESTERN EUROPE THAT IT BECAME INTERESTED IN THIS MATTER.
Not that it would do much, of course. It wants Poland to resign of veto for a mere promess of support in the future

Russia changed its national holiday to a day commemorating anti-polish uprising, as well. I wouldn't mind, really, if it wasn't accompanied by a serie of moves directed against Poland - and other eastern european nations that try to break free from it.
It's not Poland that has problems with Russia.
It's Estonia, Latvia, Lithuania, Poland, Belarus, Ukraine, Moldova, Georgia. Even Armenia is not fully content with them.
The one who created this thread asks like a guy who, when hears "help, help, he wants to kill me" from his neighbour, next day goes to police to inform them that his neighbour is shouting at nights and he can't sleep.
Germany. Now PiS is anti-german, that's true. But Germans are giving it lots of reasons to complain. The baltic pipeline. Denying return of polish works of art robbed during ww2, while at the same time demanding return of artworks that were present in modern-day Poland when the war was finished, and were thus given to Poland by the Potchdam treaty. The problem of Erika Steinbach and the likes of her is bloated, but it exists. For those that don't know: after the end of ww2, Poland losts its eastern half, while got the eastern edges of pre-ww2 Germany. Poles were banned from the pre-ww2 eastern half of Poland, while Germans were banned from what became Poland as well (it wasn't polish decision, but of the Allies). In Poland, obviously, there was no possibility of creating organisations of Poles banned from USSR.
But analogical organisations flourished in western Germany, demanding revision of borders, return of Germans etc. It was only in 1990 that Germany finally accepted post-ww2 borders. Erika Steinbach, the current leader of the expelled organisation in Germany, voted against it. The organisation was, and still is, influential in german politics. Also, new organisation appeared, including Prussian Trust, which demands return of former german property.
Kaczynskis demand guarantees of that Poland will not be bothered with such stuff. I don't think it's really needed, it's a populistic demand, but I don't know why couldn't Poland be given it just to rest this case rest in peace.
On the other hand, there was the voting issue. When Poland entered EU, it didn't receive warm welcome. The economical conditions weren't generous at all, but we were told that at least we're getting quite some votes in european parliament. Now it was changed, reducing polish strenght drasticly, while making Germany much stronger. I don't see anything wrong with not being pleased with that. Kaczynskis actually didn't want Poland to have relatively more (or more precisely "less less") votes, but not to let a couple of the biggest states to have all the power in the EU.
Our FM, miss Fotyga, is an idiot. But Poland is not responsible for conflict with Russia, and not clearly for the conflict with Germany.
Kaczynskis are horrible, and in Poland, they are doing unimaginable stuff, but in relations with others... Sure, their politics are clumsy. They are unable to convince others to their point of view. But they are not wrong.
That You want to kick out Poland just for not agreeing with (most of) EU is very strange and un-democratic. there are other, smaller, states that are often not content with the attitude of France, Germany etc, but they are afraid to protest. because if someone wants to do something that public opinion in a couple of the biggest EU nations finds wrong, he's being attacked furiously, as Poland was in some cases.
France and Germany are not afraid at all to lead separate and egoistic politics in the EU. But heaven forbid if someone else has his own opinion. Such country 'misses an opportunity to shut up", as nicely said ex-president of France.
