That would make actions on behalf of Turkey faster.
Remember that in WW 2 Japan attacked USA when US goverment made an oil embargo against Japan.
An embargo -like the one that today Germany makes (military technology)- would force Turkey to export violence while its military power is still intact.
Remember that Iraq was the 4th stronger military power but after few years of embargo that force was 0!
Erdogan knows that very well. An embargo would accelerate Turkish people in west europe revolts. Those EU countries would force to exile-sent back to Turkey- those people.
Turkey would have 6 million more angree fanatic Erdogan suporters that would demand "lands" to live. Turkey would listen to that demand and would try to expand to Greece and Bulgaria ussing Albanian extremist and Muslim Bosnians as "the 5th phalanx" making Balkans a chaotic battlefield. Hungary hates Serbia and Greece, Romania hates Bulgaria and Austria is too far away and too weak and hates all balkans. So no help will come to Balkans against Turkey.
Erdogan knows all these possibilities and plays the card of blackmail very well.
