He seems to be grumpy and mean. If those are answer choices though, I'd have to say it's 'eager to pick a fight', 'intimidating', and 'commanding of respect'.
Character traits are words that describes someone's personality and qualities. For example, if someone likes to kicks animals for no reason and hurt those weaker than them, they're described as cruel and mean. If someone gives money to the poor and helps others in need, they're described as kind-hearted and warm.
He called the imaginary barrier the "Iron Curtain". He used this image to oppose the Soviet union expansion, and keep in communism in check. Hope this helps!!!:)
