Just to be annoying in the south China Sea.

No

China won't be able to attack the US for 30 years and that's if we do nothing

And if there were an invasion launched it would come from Canada.

Not Canada itself.

canadians are peacefull thou

Canada would not be able to support an invasion

But just as a theatre.

what will they attack us with maple syrup ?

You're stupid.

China couldn't get troops into Canada in the first place.

Oceans = completely 100% the territory of the US Navy

Overconfidence was the fall of many nations and empires.

Any hypothetical must not ignore this

We have a navy literally 40 times the size of theirs

We wouldn't let a Chinese army cross the ocean

For any reason

Even the current administration

To assume that nobody has made any progress aside from the USA is sheerly asinine.

And

For your information

Navy is the only thing that matters in war.

Chinese don't have a decent one

The Canadian DND has a lot of Chinese nationals in it.

And won't for 30 years

And we share intelligence with you.

You cannot secretly move an army.

No, but the goal of China in a conflict would be to make it such a devastating loss to attack, that it wouldn't be worth it short of war.

Yes

China would win a defensive war

But can't project force

Would be to win by attrition.

Especially to North America

Slowly widdling away at morale and motivation.

Chinese military is a regional one

They cannot attack beyond their region

daily reminder the USA is cancer on this earth

They simply do not have the infrastructure or the ability to defend large oceanic troop movements

I just don't think underestimating your enemy is good.

You should always assume there is some end game in the works.

They physically cannot secretly move an army
