Björklund said pumping more money into the Swedish Armed Forces is not sufficient. Instead, he called for a return to "the old doctrine" of defending Sweden's borders.
Russia's conduct in Ukraine today could be repeated in the Baltic states in the future, claimed Björklund. In such a scenario, the Swedish Baltic island of Gotland would be a key territory, he said.
Björklund added that the government led by Sweden's former Social Democrat prime minister, Göran Persson, had made a "big mistake" by pulling military presence on Gotland.
"We do not need more full-time staff, we need the possibility of calling in reservists. We need a combination of full-time staff and reservists," said Björklund, who also argued that events in Ukraine have highlighted the need for Sweden to join Nato.
