Poland has accepted a ton of Ukrainian refugees earlier this year, in many cases (mostly due to manpower and procedures not being in place to deal with such a huge event) skipping the paperwork to ease their transition. But that was a crisis that didn't affect the rest of EU so of course the fact that Poland did this means nothing when deciding quotas and pointing fingers when dealing with Merkel's mess.

The situation in Ukraine was shit, but even the sources in this linked article estimate the numbers at hundreds of thousands.
I'm leaving this here just to counterbalance the sentiments any rash decisions or comments about the Syrian crisis might create. Poland isn't nearly as shit as some media outlets would have you believe when it comes to welcoming people who need help.
