Poland diplomatic offensive in the USA

In the case of the president of Poland we are talking about many authoritative meetings on 21-25 September. During this time, the UN General Assembly will be the organizer and host of the Summit of the Future, which will discuss issues specified as the current global situation, safety and development. On the another hand, the almost 10-day journey of Minister Sikorski seems to be more focused on safety issues and strengthening transatlantic ties.
