Cooperation in Nato is lagging because of Turkey's requirements, and the secretary-general dare not guarantee solution in London.

the Fronts are pulled hard up between the allies in Nato before a summit in London, where Turkey has threatened to block an important step in Nato, if not the rest of the countries will formally recognise one of the turks important matter.

Turkey requires that all allies formally endorses their view that the kurdish YPG is a terrorist organisation.

the Nato secretary general, Jens Stoltenberg, can not guarantee that the 29 members come to agree on it at the summit in London.

I can't promise. But I can promise you that we are working on it. However, it is not the case that Nato does not have a plan to defend the baltic countries, says Stoltenberg.

Currently blocking Turkey so Nato defensive plan for Eastern europe.

the Problem for the allies is that the members of the kurdish group YPG has been frontsoldater against Islamic State in Syria and thus been sahabet an important ally of the UNITED states and the european countries.

the Polish president said during a special in London, that he trust that can negotiate a solution. Poland is particularly concerned that forsvarsplanen in Eastern europe, will be adopted.

Nato is an alliance with almost 30 member states, and there are many different interests.

- We can discuss it, says Andrzej Duda. He confirms that he before the summit has held a meeting with Turkey's president, Recep Tayyip Erdogan, on the matter.

Turkey's president talking like a man who is not inclined to move one millimeter on the Turkey important agenda.

- If not our friends in Nato agrees to call them, which we consider as a terrorist group, a terrorist group, then we will go against everything in this issue, says Erdogan, referring to the forsvarsplanen.

Lars Bangert Struwe, who is the secretary general of the think tank Atlantsammenslutningen, estimates that the allies can negotiate and find a compromise.

- Turkey has a perception of kurds as a security issue for them. They want us to understand it. But we have difficulty, for we do not have the same position as them, he says.

There are, he says, a big forståelsesproblem between the UNITED states, the european UNION and Turkey. This is due not least to the turks for decades, has been involved in a bloody conflict with the kurds.

- We can probably not be completely agree. It may be that you will land on a middle ground, where you talk about the kurdish terrorists - without a just regard to the specific organisation, says Lars Bangert Struwe.

The Danish government has also criticized Turkey, after the country bombed the kurds in Syria in the autumn.
