Spain, Germany, Brazil and France are all seasoned winners when it comes to the world cup and I believe this year's own will be no different. I also have faith that Portugal can do something this time around and trust that Ronaldo along with his comrades will do something special.
Spain had been impressive in previous years and no doubt will be do their best to carry this year's cup.
Ukraine will have a lot on their plate when they meet Scotland as they are still being distracted by the war, but I believe they will be worthy opponents for Scotland even if it won't be on their soil.
i think spain is not as strong as in the past, germany is not as strong as in the past, brazil is not as strong as in the past... in this list of countries you mentioned i just agree that france is more strong. In this world, strong teams are:
Belgium - they have a very strong team that can win world cup
England - they have a strong team this time that can win world cup
Argentina - also has a strong team that can win world cup
Brazil - they are not as strong as in the past but they have a chance to win the world cup
