What is the meaning of "brace" in the following excerpt from The Great Gatsby?
"When we pulled out into the winter night and the real snow, our snow, began to stretch out beside us and twinkle against the windows, and the dim lights of small Wisconsin stations moved by, a sharp wild brace came suddenly into the air. We drew in deep breaths of it as we walked back from dinner through the cold vestibules, unutterably aware of our identity with this country for one strange hour before we melted indistinguishably into it again."

"Brace" is a word that does imply a kind of include, however virtually the effect of the passage is talking approximately the unexpected gust of wind that causes Nick to shiver and to emerge as cold and privy to how freezing it's miles. It is vital to keep in mind the context of this passage. This is after Gatsby's funeral and is whilst Nick is remembering his days growing up in the West. Nick recalls one unique Christmas whilst this sharp "brace" passed off.

Something this is bracing (stimulating, invigorating). "Bracing" is usually used with the outdoors, and frequently refers to cold.

the speech this question is referring to is president kennedy's special message to the congress on urgent national needs, may 25, 1961

kennedy responds in a very direct and concrete way to those thinking that communism is a positive system:

"yet their aggression is more often concealed than open. they have fired no missiles; and their troops are seldom seen. they send arms, agitators, aid, technicians and propaganda to every troubled area. but where fighting is required, it is usually done by others--by guerrillas striking at night, by assassins striking alone--assassins who have taken the lives of four thousand civil officers in the last twelve months in vietnam alone--by subversives and saboteurs and insurrectionists, who in some cases control whole areas inside of independent nations." (kennedy)

president kennedy presents communism as cowardly, as a hidden and treacherous weapon that strikes from the shadows like thieves, he represents the system as not even being capable of showing and open and overt attack or confrontation. to finish up the response, he expresses that the system attacks even a country's idependence and freedom.
