We should trade with them and be just with them, but we must not love them.

there are different types of love, many are inappropriate for the Muslims to share with the non-Muslims (unless they should be their blood relatives or wives etc) and obviously the love of the brotherhood of Islam is a very important thing that must supersede any ties with the non-Muslims

but I think to say that we should not love the non-believers at all is an overstatement, they are still children on Adam and our brothers and sisters in humanity.

If you look at the Awlia many of them (such as Mevlana Rumi (ra) (ra) demonstrated a type of love for all human beings and I don't think they were wrong.

With Rumi it was what you may call agape love (something like universal mercy), it was something that enabled him to speak to and benefit the non-Muslims in a very gentle way compared to many modern Muslims would speak to them, but it was not passivity or weakness, nor was it the cauise of anything against the Shariah nor was it something that prevented Rumi engaging in Jihad (and killing many Mongols), but I would say it was very definitely a type of love.

We must not become dependent on them.

If only Muslims had not forgotten this.

Be harsh with the hostile kafirun not all of them indiscriminately, and wisdom must be used we cannot alienate others because of our harshness.

spot on.

Our harshness should prompt them to leave kufr.

personally I prefer a carrot to a stick in most situations. so did Rumi (ra) and strangely enough thousands of Christians and Jews became Muslim through him.
