The same policy of preventing a new maritime Power from starting in the Baltic was acted upon by Sweden and Denmark.
"Who knows not that the Emperor's attempt to get a seaport in Pomerania weighed no less with the great Gustavus than any other motive for carrying his arms even into the bowels of the house of Austria? What befel, at the times of Charles Gustavus, the crown of Poland itself, who, besides it being in those days by far the mightiest of any of the northern Powers, had then a long stretch of coast on, and some ports in, the Baltic?

The safest line of policy would be to return to the treaty of Itolbowa, and to suffer the Muscovite no longer "to nestle
