"The main consequence of this [possible] development" could be "a continued increase in military tension in the Baltic Sea," Valtersson said, warning that "it will also increase NATO's ability to close the Baltic Sea to Russian shipping."
"Another impact is that Tomahawk missiles with a range of 1,500 km (932 miles) will be permanently based near Russian territory and have longer reach. This could of course be achieved with a permanent deployment of [the Arleigh Burke class of guided] missile destroyers (DDGs) but they would be very vulnerable to attacks from Russian anti-ship missiles," the expert said.
"This would, of course, be a breach of international law and could be seen as a de facto declaration of war. That kind of statements and ideas [….] are unfortunately new and dangerous steps towards large-scale open conflict in Europe," Valtersson concluded.
