You don't actually need a trade deal with a country to trade successfully with them (hopefully I don't need to give examples of this).

I think you overestimate how long it takes to sign a unilateral trade deal when the parties want to make it happen. The reason the EU trade deals take so long is that 28 countries have to agree on the EU side (which will indeed be a problem for Brexit, but hardly the UK's fault).

Non strategy? As previously stated, we have a net trade deficit with the EU and are the EU's biggest export destination. Do you really think BMW group etc are going to want to stop selling cars to the UK?

Also as previously pointed out any import/export detriment to the UK from increased tariffs will be offset by the corresponding tariff reduction when trading with the rest of the world. That's not the case for the EU.

That's without considering the money we'll save on contributing to the EU budgets.
