Of course, because it's extra capital for Poland. Why wouldn't we negotiate to get billions of dollars?
There's countries far poorer than Poland in terms of nominal gdp, ppp, etc yet they chose to give the money to Poland. Why? Because our country uses the money far wiser than say Greece, Portugal, etc. and gives investors the type of ROI with minimal risk that they seek. Also, they gave them additional money because they saw Poland was paying it back. It's the same basic principle of banking if you borrow someone $1mln and they repay it on time, you're going to actually encourage them to borrow the same amount or more. They could've gone to far poorer countries and gave them money for 'development' yet they chose Poland because they knew they'd make a good ROI with far less risk than other nations. The problem is while this bought an influx of FDI and raised living standards, it has put key industries in foreign, and hence potentially subversive, hands.
Also the 'loan' that world bank gave Poland wasn't even a full 1 bil usd. Furthermore, it was to spur FURTHER growth
"The challenge for Poland is to sustain such impressive growth." said Theo Thomas, Lead Economist and the Task Team Leader for the operation. "The reforms supported by these loans will help ensure that the economy remains competitive and flexible in the face of potential economic shocks. This will support the recovery in investment and employment to ensure that Poland's prosperity continues to be widely shared."
.It has challenges to face which have to be addressed
Yes, like asserting our sovereignty and independence towards the EU, gaining more populist allies, letting Italy join V4, refusing entry to all illegal migrants, people who don't have a visa, keeping our society socially conservative and Christian, etc., and buying up more shares in strategic industries like media and banking. Also, Israel needs to be taught that they don't have a monopoly on the Holocaust. Perhaps that could be a new twitter hashtag? #IsraeliHolocaustMonopoly
