This is how many more soldiers and investments Europe needs to protect itself without the US
Simply raising the number of troops might not be enough, Luigi Scazzieri, from the Centre for European Reform tells Euronews.
"Europeans need to step up their defence whether the Americans leave or not".
"To generate credible deterrence, you need to have more capabilities, particularly those on which we rely most on the US: Long-range missiles, aerial defences, aerial supply, air surveillance and transportation, for example", Scazzieri added.
