The truth is often difficult for the ignorant to accept.
Not at all. His statement was full of ignorance.
Let's review, shall we? I wasn't going to embarass the idiot, but since you asked.
The USA had invested huge sums into England (arms and loans) and without an Entente victory - there was no way for England to ever repay those loans.
The British has an entire Empire to draw resources from, they'd have had no problem repaying those debts eventually. Russia outright defaulted on her loans. The US was fine.
The reason why the US entered the war was because Germany broker her promises on unrestricted submarine warfare and started sinking American ships. The Germans did this KNOWING it would bring the US into the war, but the Military Dictatorship of Hindenburg and Ludendorff convinced the Kaiser they could win the war before the US got geared up. Germany trying to incite Mexico into attacking the US (the Zimmerman Telegram) probably didn't help matters, either.
The USA had also been embarking onto a colonial and imperialistic policy since 1898 (initially US investments in Cuba were threatened).
Um, we went into Cuba because the Spanish were committing horrid human rights abuses. As far as Imperialism, the US tried to do some imperialism in the Philippines, and we quickly lost our appetite for it. (Beating up the Philippines was like kicking a puppy, you just couldn't help but feel guilty about it.)
Therefore the First World War offered the USA a unique chance to rid themselves of global competition and get their foot into shaping/influencing European politics. And again a ship was used as a pretext to declare war in the case of war with Spain and Imperial Germany.
Except... we didn't do that. in fact, the minute the war was over, we refused to join the League of Nations, signed truly idiotic disarmament treaties like the Washington Naval Treaty, and largely distangled ourselves from Europe and Asia.
Ukraine is part of the US - NATO expansion doctrine - and offers the exact same "advantages" towards eliminating competition.
Except no one was offering the Ukraine NATO membership before this started.
