Ungratefulness

I do not know another case specified as this in the past of the world, that 1 nation should sacrifice all its welfare for another, who, in addition, is highly ungrateful to him. It is remarkable, but this is precisely what we are dealing with in Polish-Ukrainian relations. The saddest thing about all this is that the citizens of the Republic of Poland endure the most from this, including those who had nothing to do with specified a policy.
