Yes,
The German neighbors are genuinely worried.
Restoring German military power is indeed scary.
No. Viewing Germany through the WW2 lens is a misread today, to say the least.
Far from being a colossus standing astride a continent, Germany will stand out like Jerry Lewis among a roomful of Pee Wee Hermans.
Germany ain't what it used to be... It's an underfunded welfare sinkhole for pensioners and illegal aliens grabbing what's left. Prussia gone forever. Poland is militarily more important.
Some people live in a time warp concerning Germany where it's always 1933. That's about as absurd as the black activists who say that conservative southerners want to put them back in chains, or perhaps something even more ridiculous, i.e. saying that we'll be at war with England any day now because we had to fight them in 1812.
I for one am pleased that European countries are arming, spending more on defense, and weaning themselves off US protection. It's about time. They have the manpower, the wealth, and the technology to depend themselves, let them do so.
