Yes, you can, you are only pulling 15 amp max on a 20 amp circuit, so there is no problem there.
No, it would not be safe. DON'T DO THIS!? If anything went wrong with an appliance plugged in…to that 15 Amp socket outlet there would be a serious risk of starting a house fire or someone could get electrocuted.
? The reason is that the breakers on 30 Amp circuits would not cut the power off if an accident happened or something went badly wrong inside an appliance that takes less than half that 30 Amp current. The current draw would be even less if it was a table lamp or something equally small.? As you asked this question here you may not really know how to handle household AC power circuits safely, so be sensible: call a licensed electrician to install the correct circuit breaker and the right size of wiring to power any new 15 Amp socket outlets you need in your house, so that you and your family can use them safely.? ALWAYS CHECK WITH YOUR LOCAL WIRING SAFETY OFFICE BEFORE YOU ATTEMPT TO CHANGE ANYTHING - ELECTRICAL SERVICE PANEL, BREAKERS, CABLES OR OUTLETS - ON ANY ELECTRICAL POWER CIRCUITS IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB SAFELY AND COMPETENTLY REFER THIS WORK TO QUALIFIED PROFESSIONALS.
If you do this work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work AND always use an electrician's test meter having metal-tipped probes (not a simple proximity voltage indicator) to insure the circuit is, in fact, de-energized.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
