First of all, if Putin were to invade Sweden, not being to be able to pay for things would be the least of our problems. Secondly, to hack our digital systems, he surely wouldn’t need to invade Sweden first. Thirdly, if he were to hack us, I’m pretty sure he would take down electricity, water supply and other crucial things before going after our payments.
