Polish authorities are looking into demanding reparations from Germany for the massive losses inflicted on Poland during World War II.

Officials are preparing an analysis of whether Poland can legally make the claim, though no one has said how much money they expect.

It comes after Jaroslaw Kaczynski, Poland's most powerful politician, said the 'Polish government is preparing itself for a historical counteroffensive'.

'We are talking here about huge sums, and also about the fact that Germany for many years refused to take responsibility for World War II,' said Kaczynski, leader of the ruling conservative ruling party.

Germany has already paid billions of euros in compensation for Nazi crimes, primarily to Jewish survivors, over the years.

'If Jews have gotten compensation... for loss of property, why shouldn't we too make claims?' said Ryszard Czarnecki, a ruling party member and deputy head of the European Parliament.

Poland's former communist government, under pressure from the Soviet Union, agreed in 1953 to not to make any further claims on Germany.

In Berlin, Chancellor Angela Merkel's spokesperson Ulrike Demmer, said: Of course Germany stands by its responsibility in World War II, politically, morally and financially.'

'It has made significant reparations for general war damage, including to Poland, and is still paying significant compensation for Nazi wrongdoing,' Demmer told reporters.

The massive suffering inflicted on Poland has been a topic of public discussion as Poland marked the anniversary this week of the start of the Warsaw Uprising of 1944.

The doomed revolt against the Nazi German occupying forces resulted in the killing of 200,000 Poles and the near-total destruction of the Polish capital.

Amid the observances, Defense Minister Antoni Macierewicz said Tuesday that Germans need to 'pay back the terrible debt they owe to the Polish people.'

World War II, which began with the German invasion of Poland in 1939, left almost 6 million Polish citizens dead and inflicted huge material losses, including the destruction of cultural treasures, industry and entire cities.

Kaczynski called for reparations from Germany when he was prime minister more than a decade ago, adding to tensions between Poland and Germany, important trade partners and allies in NATO and the European Union.

His party, Law and Justice, has a nationalist bent and is often critical of Germany, accusing it of unfairly dominating other EU members.

Demmer said as far as Germany is concerned, 'the question of German reparations for Poland was dealt with conclusively in the past, legally and politically.'

But Polish Defense Minister Macierewicz says communist-era Poland was a 'Soviet puppet state' whose decision is not necessarily still valid.
