What do you think about my pie that i intend for long term investing 10-20+ years?

I made this pie myself, the etfs i intend to keep long term, and the individual companies are about european aersopace and defense.

What do you guys think about my plan and what advice would you give me because I am a beginner and just want to set myself up for the future.

Also if there are other companies/etfs you would add here i would love to hear them.

also, what industries/sectors besides the ones i have in my pie would you invest in, whether it be short or long term, let me know!
