Russia is at least a rival and at worst a threat. In any case, encouraging them to spy on us is not something that should be said - even in jest - by a candidate for the Presidency. Trump once again has demonstrated that he can't be taken seriously on matters of national security.
I mentioned Watergate above, and it bears repeating. Maybe Russia did hack into Hillary's emails. Maybe not. We know for certain that Wikileaks hacked the DNC and deliberately timed the release in an attempt to undermine the US Presidential election. Shades of Watergate abound. That time it was a domestic plot, and there had to be a physical break in, but the intended result was the same: To undermine the US Presidential election. The actual result was a sitting President resigning in disgrace and the entire nation losing confidence in their government for a generation if not more.
This is serious stuff we're talking about here, but to you, and dismal, and Donald Trump it is all a big fucking joke.
