That's fine. It's the same as to say, claim that Brexiters are "covertly pro-Russian", and it's fine when half the people are against EU, coz if everyone was thinking the same, it's same as no one thinking at all.
Great Britain is an island. It's not between Germany and Russia. If you're a country between powerful neighbors with history of waging wars on you, you either need to be very powerful, or you need an alliance. Poland is far from powerful. It's not going to get powerful in the foreseeable future. Therefore it needs an alliance.
