No...
This quote should tell you all you need to know:
"I am for free commerce with all nations, political connection with none, and little or no diplomatic establishment.
And I am not for linking ourselves by new treaties with the quarrels of Europe,
entering that field of slaughter to preserve their balance, or joining in the confederacy of Kings to war against the principles of liberty." --Thomas Jefferson
Jefferson would not support our involvement in various global alliances and would definitely be against America engaging in regime change/nation-building. However, he wasn't a complete isolationist and was/would be today a large proponent of increasing free trade with other nations. Obviously your post wasn't serious, but why not respond with evidence anyway
